2013 Fiat 500 Abarth #2 Owned it two years - Suspension, intake, exhaust, downpipe and tune - Good for roughly 240 hp, though with non-stop issues, it never produced anything near those numbers. Only thing it had going for it was the exhaust. It sounded excellent and I could get it to backfire and throw fireballs on command. Traded it in for the Z.
2013 Fiat 500 Abarth #1 Owned it less than a month (4 days before first payment due). Intake only. Moron pulled out in front of me and totaled both cars. His Toyota Corolla was much worse. Traded the '91 Miata in for this.

There's many more, but I'm going to give it a rest for now before I piss you all off. LOL It's time for me to...
