The BMW M3 is a true BMW enthusiast's must-have. I bought this car at 90k miles and have driven it 30k more without many major issues - just one dead gas pedal which cost me ($120, 5 mins to replace), four oil changes ($70 each), air filter, and a few other small repairs (window regulator $200, convertible top sensor $300). If you can even remotely work on cars, you can SIGNIFICANTLY reduce the cost of ownership and heighten its reliability. I commute with this car everyday and it's fast, fun, practical, and great in stock form.
What else do you buy this car for besides its handling, performance, and prestige? It hides its weight very well. Short of the Ducati 999, it's the funnest, most exhilarating toy in the garage. Oh and I commute with it too.
Where am I going to hang my coat? And tell BMW dealerships to lower their prices - it is far less expensive than they charge you to take care of this thing.
