I would have to say my Saab takes up the other half of my obsessive side. In the winter when it's snowy outside I tend to focus on audio and in the summer it's the car. I have sunk thousands into tuning my 1994 Saab 9000 Aero, which now puts out 280 hp at the wheels and 320 pounds of torque. Not bad for a four banger.
Cheers,
