Please don't give your teen a performance car
The recent crash in Princeton that killed two 17-year olds (so far) after a 4am high-speed crash with 7 kids in a 5-seat car is tragic. It also reminds me that cars may be much safer than they ever, but teens still have no business driving a 260-hp turbo Mazdaspeed3. I haven't done the exact math, but I'd wager the power-to-weight on the MS3 rivals the Mustang 5.0's that were what the rich kids got back in the late 80's, with similar deadly results.
Tragic, and maybe somewhat preventable (at least it would be a slower crash in a normal Mazda3)
