2008 BMW 5 Series 535i 4dr Sedan (3.0L 6cyl Turbo 6M)
I bought mine used with 40000 miles and with 65000 miles now. I am very happy with the performance and reliability. Nothing has gone wrong with it. I recently put brakes on at an independent BMW shop for $1200, complete.
When I punch the accelerator the car is a rocket. It looks great (deep sea blue with natural brown leather seats and tints windows). The seven spoke alloys with the sport package are perfect.
High performance engine, decent fuel economy, no reliability issues.
