Know what you mean.
I have a 2000 M5 with only 52K on the clock. Jet Black with caramel leather interior.
I also have an M3 but once I bought the M5, the 3 just sits.
The M5 is the best sport sedan on the planet, bar none!
Unfortunately in Washington DC Regional traffic, I never get past 4th or 5th gear.
Cheers!
