Do like I wish my father would have done and just buy the little sucker an Fbody!!!!!!

Screw mpg and insurance costs.....he will love you forever!
You could also fool him and get him a truck. He'll think you ended his racing dreams.....until the mods start to come. Then he'll be taking people's money and he can even do some hauling of various things in the bed for you(see everyone wins)

My insurance is super cheap, but of course they have no idea what the truck has become.
