panthro said:How so? His Focus gets 20mpg at best, goes through tyres at a stupidly fast rate, a new clutch (the clutch itself, not fitted) cost £500 and brake pads and discs cost a fortune too.
You can spend nearly £1000 on a set of four tyres for an M without blinking, most parts are horrifically expensive.
It offers supercar performance but it comes with supercar running costs. You're looking at least double the cost of the focus, probably a minimum of £5k a year to keep an M5 in decent shape on the road in consumables and servicing costs alone.
I looked into it in far too much depth when I was toying with buying one.

But for sheer driving fun, the Escort Cosworth is gonna be miles ahead.

Having said all of that i would have the M5 over an RS, just i would have an M3 over an M5 for outright day to day fun.
