Do you think they're somewhat cool and fast for a kid?

nah thats not a good idea, there not cool kids suvs, you want something thats either sporty or fast or a real suv. not something that middle aged wemon drive

1they cost a lot to maintain
2 they look like they are a wanabe of the x5
either get a x5 or a truck or better just a coupe

have fun paying for those expensive bmw parts when your kid destroys it.

I don't think it cool nor fast. Either get a regular 3-series or a regular truck

ain't that a little too luxurious for a teenage boy?
