17 and choosing between a new range or a 745 beamer, i'm jealous... To be honest you don't have to worry about reliability. I mean, if you can afford these cars, you are obviously going to trade it in within 5 years anyway, so get whichever you like better. And the M5 is nice, but I doubt this guy wants to wait a year plus on a list to get one. Whatever you get, up some pictures, I'd like to see what people on this board are driving.
