Question: what is the difference between bmw m3 and m5?
Answer: The M5 is, of course, bigger than the M3, but not so much as you might think. ... The M3 isn't much smaller, but sits four in comfort, has a boot that's only 40 litres smaller and is nearly £18k cheaper. It also drives with more verve and precision. We'd have M3 over M5 every day of the week.
