1A Auto Reviews | Customer Feedback
"I am very happy to have found you on the internet. Freight cost is a big issue here in Alaska as is parts delivery. Most parts places only ship Fedex, UPS or some other delivery service and also charge outrageous freight prices. I ordered a battery tray from you and you mailed it to my P.O. box (we have no delivery here in Healy) and charged me nothing for freight! I tell anyone that is looking for parts to buy from you, you're a lifesaver."

"I own a 1999 Daewoo Leganza. My Camshaft Sensor broke, and since my car is aftermarket, I couldn't find the part anywhere. After a Google search I found 1A Auto.

"I found the replacement taillights for my 1990 454SS at 1A Auto for the best price anywhere. I would recommend them to anyone.

"I bought a set of door weatherstripping for my IROC, after being recommended by a friend.
Buying went very smoothly, and I received the product quickly.

"When I ordered the Fog lamp for my 2004 Dodge Ram, I called other places, including the Dealer. They (the dealer) wanted $141 plus change for the part and tax of course.
I called 1A Auto after visting their web site and was told it was about 80.00 +no tax, and free shipping.
Well that was a "no brainer." I called on a Monday and placed the order. I was told that it would take a few days to process and another day or so for the order to reach my house.
That same Thursday I got a package and was wondering who or where it was from!
I was totally caught by surprise to find it was the part that I had ordered!!!!
WOW!! Thank you for the promptness and the quaility of the product. They were identical to the part I replaced!!
