2007 BMW 3 Series 335i 4dr Sedan (3.0L 6cyl Turbo 6M)
Bought my 335i after begging my wife to drive her 535i for 6 months. I chose the sedan over the coupe because I do have people in the backseat frequently. The car drives like a rocket on wheels. Fast, but also very smooth and refined in most driving situations. It is the only car I have owned in 45 years of driving that excites me every time I start it, even after a year's ownership. An unexpected plus has been the gas mileage. It has consistently delivered 22+MPG city and 30 on highway cruises. It has been extraordinarily reliable with only routine dealer visits all covered under warranty.
The premium package gives me plenty of luxury and features, but I also got navigation and Sirius radio. These are a must for long distance driving. The iDrive, which is frequently maligned, is not that hard to master and offers amazing control of all the car's features without a lot of buttons.
Can the run-flat tires. Increase the size of the sun visors (maybe with an extender).
