good and quick

The description for the Trimax adjustable receiver hitch did not always include the drop and had to be gleaned from the part number.

good price

I was looking for a part for my Mallory distributor at a fair price. I called around to my local speed shops and they all had to order the part, so I went on line. With a little research for the best price here, at Autoplicity. I ordered the part last night and it has shipped 24 hours later. I like that. I have bookmarked Autoplicity so I can use the again. Thanks guys.<br><br>Jim

Lightning fast service! Good prices.

Great company to deal with. Had a question and called the 800 number and spoke to a person not a computer..... a real pleasure to deal with.. A plus in my book....
