Great service after purchase
I purchase headlights for my 99 Cadillac Seville, and when the shipment came to my house, unfortuntely the side lights on the assembly were not in the packaging. I called customer service and they did not hesitate to get the remaining pieces to my package to me, after confirming a few things. Most companies would fight and refuse to straighten the order out and would just leave the customer stuck, but 1A auto showed what the "A" stood for, grade A service through making sure the clients are tooken care of and happy with their purchase. Id recommend them over my auto parts after market retailer. Awesome, is a word I used to describe 1A and the new look of my 99 Seville!
