1aauto has been a pleasure to deal with
I have ordered several parts from 1A Auto over the years. All of the parts seem to have held up and work as they should. Only one instance that I have had to contact customer service and it was a real pleasure and everything was taken care of to my satisfaction with absolutely no problems.

First Class Service and Information - saved me a lot of $
I was faced with a costly problem with my wife's 2004 LaSabre! The driver's side window stoped functioning. She was told at the Dealer that it would take $700.00 to fix it. I went on line and found your video on how to fix it myself. Even thought I am 87 years old I knew I could fix is myself after watching your video twice. I ordered the part from you and had it in 3 days. The next morning I had the door window fixed and running smoothly in lexx than 30 minutes. Great solution and service. D. E. Mann

Replaced window regulator.
I purchased a replacement window regulator from you guys after doing some research on how to do it myself and foundd your video series. Watched the video and ordered right from your site. Not being a "car guy" but a handy guy, your video showed me how simple it is to change it out. This is key because I received a quote of $350 + to have it repaired from my local repair shop. The part I ordered was $50 and some change and it took me all of a half hour to fix it myself. Thank you 1A, for showing us beginners how to and to save some $$$$. Will definitely buying more parts from you in the future.
