Compared against the Skyline, the various cosworths and the Makka, the M5 is the cheapest car I have ever run. Period.

Yes fuel is expensive, but its easily paid for by the fact it doesnt use oil or need its oil changeing every few thousand miles.

Tyres are expensive initially yes, but my backs are just about ready for replacement now after nearly 15000 miles, lots of them at the Nurburgring too. The fronts have probably got the same again left in them. So expensive initially, but they wear 100% evenly so last a long time.

Brakes, same again, I put some pads in when i bought her. They are still all in there. The cossie needed new ones after every fooking ring trip. LOL
