We have had our 500c 5 spd on the road for 6000+ miles now. Not a hiccup (except a minor wiring issue in week 1 which was quickly resolved) and are enjoying it more than ever. People approach us just about every time we drive the car and are totally fascinated with it, how the cabrio top works, etc. It may be my imagination, but the car seems to run stronger the longer we have it. Love the Bose stereo. It provides more grins per mile than just about anything with wheels I have ever owned. We drove it over the holidays up to the mountains to my brother-in-law's cabin (7000') and just blistered the twisty roads. We did go faster downhill than up, but hey, you can't have everything for $20k.
11000 miles ( 17,600 KMS)
Just had one of my brake calipers replaced because it was sticking and causing the rotor to rub a little, also had my radio replaced because the paint on the radio presets were almost all rubbed off. Also had a new drivers side skirt replaced because the old one kept falling off..
Other than those small issues its been mechanically and electrically perfect
1. the USB port ceased to work for some reason but was resolved
2. the dealer mechanics (@ Fiat of McKinney) incompetently left their tools in my engine bay and the engine fuse box open and exposed from that fix i did not notice until i opened the bonnet to check oil
plus the two recalls
