That's a good looking car, and suspensions unlimited builds a nice car.
I don't mean to discourage you,
but if you want something dependable,,, Stay-Away from Rotary motors.
They haul-arse, But they're like a 2-stroke. the maintenance is demanding.
I think the rotary motor is one of the least dependable motors out there.
There are many other better choices in my opinion.
My car has a Honda 3.5 V6, It's super dependable.
Other good motors are Subaru, Ls series chevys.
More of my pennies for ya.
