462 bhp and 328 lb/ft sounds nice, though as you say, $25k is a lot of bread. Still, it is an impressive total package, a sensible total up-grade including brakes & suspension, plus shorter gearing, not just bolt-on power, so it seems reasonable value to an outsider.
Can you clarify re 'factory installed at authorised BMW dealership' - I presume it is Dinan's factory and warranty, not BMW's?
