Old bike maintenance, especially one with six carbs, is a PITA! I'd much rather have the new CB for the same reasons I bought a '06 Scrambler over a '67 Triumph and a 620i Monster over a overpriced, old Desmo. Better brakes, handling, electronics that work, reliability, fuel injection, no leaks, no dry rotting rubber parts, dry rotted/fading plastic, replacement parts availiblity, aftermarket support...I could go on.
Who cares about the money and depreciation? If I was that worried about it, I would have put it into gold or Apple stock and not something fun with two wheels.
