So I was thinking about the Mustang. I love the car to death, and it's affordable, but it's got me tighter on money than I wanna be due to insurance and gas, mostly, but also, obviously, the car payment.

I'm halfway considering trading it in. I'm trying to think of a logical yet fun ass car to possibly swap over to.

Cars I've considered:

IS300
Saab 9-3
BMW 3-series

I don't like the 3series idea because of the higher mileage it would likely have. The 9-3 and IS3 I really like because they're fun, comfortable, nice, better gas mileage, reliable, and pretty damn importantly...4doors...

Thoughts? Other suggestions?
