Well, I might drive a Mark II Supra.. Those seem nice from the outside. A Yaris is not a Mark II Supra, and idk about the interior layout of the mkII so I cannot say for sure if I would be happy with it.
The engine sound might be a problem though, I do not think I have ever heard a good sounding supra.. so that would require an engine swap and exhaust work, but idk how much room it has in the engine bay for such things.
Firebird on the other hand has LOTS of space under the hood and even though it currently does not sound very good, it sounds better than something Japanese.
(this only matters because I have to actually drive the car and I do not want to drive something annoying)
