I think the high repair costs are really what pulls the resale down on the 600's. But then again if you figure you paid 120k for an S600 new you drive off the lot and there goes around 40k off the value. Keep it for a few years and it keeps going down. Also I've noticed in Texas and FL all the v12's seem so much cheaper it's the same way with the 750il. But I'm sure if you took one to Nebraska it would be a diffrent story because of the fact there are not as many flagship models there
Just my 2 cents
