For some reason I am not into shape of sport cars. I will concur though, the E39M5 is quite a car. Even a smaller M3 is a beast... and it has a nice classic shape.
If I had spare $60.000 I'd actually spend it for neither piano or car, but put a down payment for a nice property. I just don't see a good reason of investing $60.000 into a car, when in a year or two its value will be about half down.
I have a BMW635csi, which in 1985 was sold for $52.000. I bought it a couple years ago for $2000. Mind you, it had less than 100K on the engine, still puts to shame all those cars out there, and has a beautiful classic shape--they don't do anything like this anymore.
On the other hand, properties which were $60.000 in 1985 at least tripled their value.
As far as piano concerned, I bought a second hand "Anton Richter" baby grand 3 years ago, made it regulated the way I need, and more than happy with that. I don't really understand why should I buy anything inferior to Steinway D (like O, L, M), which any way would not be a "real thing".
I don't really care what to practice on. Whenever I want to play a good instrument I just play a concert
