Most of the Jr's running 7.90's parents have close to 15K in them. Once they turn 18 they can no longer race them and the resell value on Jr is pennies on the dollar, why? Because alot of parents want the best for their kids so they might buy a used jr to start with to get the kids feet wet, but then they have to buy a new one so THEIR kid has the latest and greatest... Put 15K in a big car and you can drive it for a very long time....
