This is the first time I ordered from Autoplicity. Very good experience overall. The prices are the best I can find anywhere online. It was shipped very quickly, and I received my item just in time before my trip. Thanks!

I bought a set of 3 MSD Ignition coils for my 2001 Impala LS 3.8 and I am very impressed and satisfied with my purchase. I got an email right away stating what I purchased and within a day or two I recieved a shipping confirmation. My ignition coils arrived fast and I had no problem with the coils been bad or broken. The coils are awesome. There is a significant difference between my old ones and these 3 new ones. The car is very responsive to the accelerator and as stated in the MSD website, the car gained some horsepower. I don't have to press the accelerator in that much to gain the power I need. I'm impressed overall.

Wow that was fast. I ordered a Pertronix Ignitor conversion kit. Not only were they by far the lowest price I could find, they shipped within hours of submitting the order. I got the shipment in less than 24 hrs, even though I ordered ground shipping. I was a little bummed that they did not offer free shipping, as I am used to with other online places, but with their fast turnaround, I am not begrudging it. Sure it might have been because they have a warehouse nearby, but it was still unexpectedly impressive. The part arrived and looks like it all there and should be good to go. <br><br>I can't vouch for their customer service, but so far I am pleasantly surprised.

Great selection of parts and great responses to orders through e mail
