The main road in England that links Exeter in the south west with Birmingham in the midlands. Infamous for it's heavy congestion and endless lines of caravans in the summer months
I know we are on the M5, I can see 400 caravans and we have moved 400 yards in the last two hours.

Probably the best car ever amazing 5.0L V10 w/ 507 HP that will blow the doors off of any asian or american sports car, and beats most mercedes (not the mclaren)...currently the fastest STOCK car available in the world.
Randy: I would sell my soul to satan to have an M5.

Check out the google video of an M5 beating a Lamorghini Galardo....(not a stock car)..O DAMN!

The ultimate road version of BMW's popular 5 series. The M stands for Motorsport. Capable of a swift 155mph, it can outrun most other cars within it's price range while carrying multiple passengers.

Just so you don't get fooled by the other definitions, the M5 was built to rival Jaguar's XJ sport and XJ exec. BMW aren't in the same league as Mercedes-Benz sales-wise.
That M5 tore <random american trash> a new assole.

OMG my vette lost and the wheels fell off! I need an M5!
