Faster shipping than I expected. Easy order process. The ignition switch was my problem and Autoplicity part was exactly what I needed at a price better than anyone else had, with shipping included. I will definitely look to them again when I need any more parts for my Monte Carlo SS.
Only slight negative would be it took a few days to get an email with tracking number so I would know when my part would come. But once I got it, found it was coming sooner than I originally thought, which was great.
