I realize satisfied is different for everyone, and i'll always be looking and drooling over new cars and such, but to be honest, i'm pretty happy with my current car. It's a 2.5L MK6 Golf. Not fast, Not the most high end features.. just a basic transportation car.. but it looks so good. It drives just fine. gives me great gas mileage, and is super useful. I can load up a 65" TV in there no sweat, and yet still enjoy just cruising around and using it for basic transport.
Can i use more power? sure.. but 185hp is good enough for me. I added coilovers, exhaust, intake, gps android headunit, a decent sub/amp and some wheels and i'm all good. So are you happy with your current car?
