1st time purchaser.
I was pleasantly surprised by the courtesy and helpfulness of the staff member which was assisting me on my purchase. She was very knowledgeable of the part in which I ordered. The order came in a timely fashion as promised. The part was well packed and NOT damaged. This why I choose 1A Auto. The other supplier sent a damaged part which I promptly sent back and noticed that 1A Auto offered the same product for a substantial savings. Again, in the future I will surely be using 1A Auto.
