Over a beer, a friend asks you what used car you'd buy if you had $30 grand. Here's a fun answer: a BMW M3.
What is now segmented into a four-door (M3) and coupe (M4) has been, over the years, both a sedan and coupe in M3 guise. Rarely will you a better combination of performance and practicality than BMW's superlative M3 sedan. In 2011 – the last year for the 4-door sedan of this generation – you'll enjoy V8 torque, a 0-60 time of under 5 seconds and an electronically limited top end of 155 miles per hour.
