The BMW 1 Series M Coupe is a limited-edition German sports car that has us considering a raid upon our 401(k). We'd also happily supply our significant others with the BMW 650i convertible. One day, however, we would wind up at a stoplight night to a couple with more money who opted for the AC Schnitzer-tuned versions of both, and our smiles would give way to frowns that lacked sufficient funds to retire.
