Bought mine in Dec 2013 with 78K miles, sold July 2016 with 109K miles. About 12k miles per year. Had headers, tp, exhaust, coils, wheels, spacers, crank pully, full audio upgrade
The plan was to keep it until I got a good enough job/promotions to get a better car. And that's exactly what I did. Got a 2014 Cayman S 2 months ago at 25 y/o
Already have springs and upgraded brakes waiting in my house to go on. Car mods are a $$$ addiction.
