they say CX-7 uses alot of gas, but how about if your not uses the turbo always, driving at moderate speeds , is it still a good buy?

I am looking to buy a honda prelude 5th gen and was wondering is the type sh or the base model better for an everyday drive and if i want to turbo it. Also what other cars have potential?

a turbo or a supercharger

i plan on adding turbo so keep that in mind
