Well, just my opinion...but...for $13,000 less...I'll take the BMW and put the rest of the dough towards something like a motorcycle or something else fun. ($13,000 doesn't justify 0.2 seconds 0-60, slightly worse handling (notice the slalom), slightly more HP, and worse gas mileage)
(Hehe, although...don't buy just yet...look what's RIGHT AROUND THE CORNER!)
