I test drove the '05 MCS yesterday and, of course, loved it. The dealership, however, also has a handful of the MC40s in stock. Apparently, they haven't been selling terribly well and are being offered at a discount from list. Normally, I would prefer to take the newer model, configured as I like, and be done with it. But, the MC40 is in one of the color schemes I'd been considering (chili red/white roof) and has a number of interesting bits that aren't available otherwise (red/black leather seats, carbon fiber dash, etc.). Assuming that I would be doing some performance modifications to the car in any event, is there really anything I would be drastically missing performance-wise by going with the '04? The only things I can think of are the different gear ratios and the LSD. Thanks.
