For that amount of $$$, you could get a new GTR, a used 911T, or you could have a new M3 with mods: an intercooled S/C, titanium exhaust, BBK, coils, tires for the same price (actually less).

The M3 will be fastest in a roll race. From a dead stop the M3 will be playing catch-up and perhaps it's all even by the end of the quarter mile. At the track who knows...the M3 has stepped it up with coils/brakes/tires but the stock GTR and 911T are formidable and which one is faster really depends on the particular track and driver competency. My guess is that for a novice, the GTR and 911T will be faster given the grip levels.

All three cars will be tons of fun.

Sure with unlimited $$$ you could make the 911T and GTR way faster. But that's not really what the OP was after.
