I mean, seriously, it is such a relief to find first a company that has reasonable prices, then is so prompt in not just getting my parts out, but also responding to me, and finally, you actually gave me back that much in the shipping charges without any hassle!!! THANK YOU so much!!!! Sterling"

"I removed everything yesterday. Your timing belt (three years old, 70,000kms) actually held up pretty well. The problem was the crankshaft seal (which was not replaced) leaked and put sludge on the belt and the entire pathway. I believe your stuff is good and will continue to buy from you. Your water pump also fine(70,000kms), same with pulleys."

-Riga, Latvia

"Got my part. I had to see it to believe it. I cant believe that $44 (auxiliary water pump) was all i spent on a part that is being sold by others between $210 and $355. This part is almost identical and iN some ways looks more substantial I am shocked at the markup on such a part and was happy to save between $160 and $300. Car is no longer leaking coolant and will let you know how it holds up."

"First, let me tell you that my rebuilt VW TDI ALH Injection pump is working great. Thanks for your patience as mine was drawing short. LOL You guys did everything one a customer can expect and then some!! Thanks for being a company to be depended on, that did everything expected, and will always be my recommendation for VW parts. Second, could you send me the E-Mail address or mailing address that I may tell them what an excellent job your company has done. I am sure that most BBB's get complaints about their members so I want to be sure to notify them about how professional your company is to work with. 50+ years in the automotive field has led me to alot of companies that give the "run around". It is so good to deal with one that is honest and true to their customers. Thanks again for taking care of my injector pump problems.

-Nassau Bay, TX, USA

"I ordered a replacement window for my BMW Z3 from your company. I received the window, but had to wait to install it because the directions stated that the temperature had to be 70 degrees or above. I live in Washington State and, although the rest of the country hit record temperatures, Washington was below average for the Spring and most of the Summer. During this time, I traded my BMW for the newer retractable hardtop Z4 and never got the chance to replace the window. I actually forgot about it and when I discovered it in the box in my garage I thought that I would have to sell it on my own. I contacted your customer service department and they agreed to accept it as a return upon inspection. I returned the window, which was in the same condition as when I received it. Your company credited my account for most of the cost and I want to tell you that I found that to be exceptional. I want to thank you for making an excellent product in the USA and for caring about your customers. I am retired Army and believe in America and American made products and you can count on me to tell anyone who will listen about the great company you run."
-Lacey, WA

-Texas, USA,

"I just wanted to follow up on some of the concerns I had expressed to you prior to buying the rear window from you. Well, today I had it installed by an upholsterer I have used for years, and it turned out perfectly!! Even though you do not offer the rubber piping around the plastic window, your border worked just fine.I am a very satisfied customer!! In fact the guy who did the installation gets asked to do lots of these and he is so impressed with your product, that he has asked me to tell him where I got mine."
-San Diego, CA

"The window was beautiful. Better than the factory window! It came with all the little things I needed to install it in a Ziploc baggie with instructions. And believe it or not, my son installed the window on the first try, 20 minutes! My husband was so happy. My brother in law buys old Miata’s and I have told him about your website. My older son is going to purchase a window for his girlfriends father’s BMW now too. I have told everyone I know here in Maryland and Virginia to check out your website. Thank you for your excellent product and trustworthy service!

"Yesterday I sent an email regarding a problem I was having with a replacement window I purchased from you a few months back, the email was sent at 7:03 AM MDT. At 7:42 AM MDT I received a call from your staff to discuss the problem! WOW!!! I am hugely impressed. This kind of customer service is OUTSTANDING for any transaction, but particularly so for an internet transaction. I don't know yet whether your window is the "best" for my application yet, but "money talks" and it is the best "fit" for me at this time. I felt a need to express my gratitude for your speedy response to my problem an compliment you on, in my opinion, customer service that is second to none."
-Durango, CO USA

"Wow. Thanks for the update and quick turn around. I sure appreciate all of your efforts."


"Thanks dave for fixing the injection pump and upgrading it. So far its working great just waiting on my new injectors from you guys to see if that'll be the final touch. Then im getting ready to intercool it. Its a fun diesel now with all the upgrades I did and still gets killer mileage. Thanks again dave I appreciate it!"
-Ojai, CA USA

"I fired it up this afternoon! Now, when I crack any injector line, the engine slows. It runs much smoother, and actually idles at a good speed (it barely would keep running before). Since I haven’t adjusted the pump or valve timing, I’ll have to say that the new injector nozzles must have done the trick….. I appreciate your corresponding with me!"

"You've been so helpful; I want to make sure you get my business. If I go through westportparts.com, is that you,too?"

"Hi Dave! First, thanks so much for the very detailed reply! It was most helpful!! Secondly, sorry for not returning the email for so long!! I purchased one of your pumps on Ebay. I am happy to say that after reinstalling the original pump of mine that you rebuilt, the car is running, happy as it has ever been. The knocking or premature ignition sound it was making is totally gone. The last we chatted, the pump had been installed at a VW shop. But, the car would not start without having to turn it over and over. Finally, it would start! I told the guys at the shop about your suggestion of crush washers. They said that they were thinking the same thing. It took replacing a couple of fuel lines as well but there it was, big as life on my invoice, crush washers. So, you called it Dave and I can't thank you enough for all of your running around you did to get me taken care of!! I am wondering about my core. In your last email, you said to send the other one back and make a note of what exactly I had expierienced with the pump. You would look at it and see if there was anything wrong with it. It has been an awful long time since I won the pump. Once again, thanks so much for your help and tutoring!! ."

"I purchased a fuel injection pump from you in July. I had issues, and wanted to get back to you on the subject. I want to humbly apologize for implications on my part that the pump was bad. I took the opinion of a large professional diesel injection shop , who came very highly recommended by my regular VW tech, whom I trust highly. It seems that after my last pickup of my car in late August, I had starting issues which got worse by the day. After about 8 days it wouldn't start at all, and was towed back to said shop. I requested that they pronounce the pump bad so I could seek compensation from your company. After a period of rest at the shop, I was called and informed that she was ready to go, no charge. Upon my request for information as to what transpired, I was told that the tech "played around with some settings". As a trained mechanic, I was fuming inside - "played around with some settings". I was told that she regularly starts right up, and she smokes less too, but the battery is dead, did you want to buy one from us, yours won't hold a charge. I went to the battery store with my warranty. They checked it out, and pronounced it healthy, and it is. Sorry this is so long winded, but I wanted to also let you know that the pieces "missing" were in the box the pump came in. My apologies for the questions I posed regarding those. I had issues with my local shop, I took their word on a number of points, and I directed fault in your direction. I placed more trust than was appropriate in my local shop, and apologize for any anguish I caused based on that. The pump seems to be working properly for the last week since I got it back. I am driving very little right now, as I just had lower back surgery, but am so far very happy. I intend to do a mileage check soon, for fun. I humbly thank you for your attention to my issues, even though they appear to not have been product related. Even when we both felt tested by the issue your staff was able to respond professionally to me. I truly wish I hadn't lain unfounded responsibility on your doorstep. I wish your staff, family, and yourself very happy holidays."

"I just want to drop a quick e-mail thanking you guys for helping get my '97 jetta TDI back on the road. I had purchased new parts to rebuild my head after the timing belt failed back in September. I now have over 5000 miles on it without any problems. I just purchased a 2005 jetta TDI wagon and will always look to your web site before purchasing anywhere else. Thanks again and keep up the good work!."
