I think there are a lot of fanbois here who have yet to experience a big repair bill for the M5.
Don't get me wrong, I have a 2003, and I love my M5.
But if your margin is so tight that you can only budget 1200 bucks a year for maintenance, this aint the car for you.
Do you know how much it cost if your VANOS goes?
Or how about the regular problems of the S62, crank position sensor, cam position sensor, valve cover gasket, fuel sending unit, leaky powersteering hoses, crappy butter soft rear sway links, or even the POS central locking? If you are not handy, can you handle the bills?
And what if your 2003 M5 with 40K miles engine granaded because the VANOS guide went while you were driving? Can you afford to get a used crate motor or have it rebuilt? It is sinificantly cheaper if this were to happen on a pedestrian engine like those in the regular E46.
Let's not even talk about the parts cost for brakes or Michelin
Pilot Sport 2.
Just because it now costs 20 some odd K to buy one, it doesn't mean it no longer requires parts for a 75K car.
