Seeing the shape though, Z3/Z4 would be fun too. Or a BRZ/GT86. So many options, without knowing what you consider fun.. hard to make a guess. For reference, here’s what a close friend considers fun.

He drives a Mitsubishi Evo 10 FQ360 as his weekend toy.
So.. suggestions without knowing where the focus lies/how you define fun, is a bit.. naff. 😀
