It is nice to make deal with. Good price and fast shipping.

Borgeson 000940

I found Autoplicity during a price search on the Borgeson steering shaft for my truck. I had never heard of them, and was a bit skepticle. But after doing some research, found that Autoplicity has a good reputation on a Jeep forum I visit.

I decided to order, and I am impresed. Extremely fast shipping, I placed my order on Saturday, and its now Monday before noon. I am holding the new part!
Overall great experience, I ordered on Sunday and got the package on Wednesday!!!
Great products and great pricing.  Fast shipping.  Couldn't ask for anything more.  A++++++ merchant.  Hope to do business with again.
