Good job.

only a few online u.s. vendors will ship to Canada,well done!

I found the best price any where for the Autolift 2.5 inch lift kit for my 04 Chevy Colorado. Autoplicity is an awesome place to shop for automobile parts and accessories.

Wow ... they not only have the best price ... but also ultra fast shipping ... the really have great customer service too .. i like that they have live chat.

Good prices so far

Easy!

seems great so far exactly what I ordered for a SBF 427 price was great

Ordered Lucas gear oil and have to say the service is great and delivery was very quick. I will recommend Autoplicity for quality yet affordable prices. will do business with again!

tried to track package and all i ever got was, your order is being processed. i did try to call on a saturday, but business hours were over. And yes i did try to email several times and they were either ignored or never received.

Like it thanks
