Cars that fit these categories

Hi all, I'm new here and just wanted to bring up a topic. I'm compiling a list of cars that must fit these categories:
RWD
2-seater
dedicated hardtop
Has perfect engine balace (I6, H6, V12, Wankel, etc.)

So far I have come up with
BMW M Coupes
Datsun/Nissan 240/260/280z, 280zx
Ferrari Enzo
Mazda RX-7s
Porsche Cayman
Ram Trucks Cummins turbo diesel

I've listed ones obtainable in the states (except it would be really hard to get a hold of an Enzo lol), but you can suggest ones outside the US too.
Can anyone think of anymore?

what do you mean by "perfect engine balance"?

Based on the criteria you posted I can think of some older ones:
Jaguar XK120/XK140 Hardtop
Jaguar XKE Coupe
AC Aceca
Aston Martin DB2
Ford Ranchero (with an I6)
Chevrolet El Camino (with an I6)
Ford Pickup (with an I6)
Chevrolet Pickup (with an I6)
Dodge D-series Pickup (with an I6)
Ford Econoline Flatnose pickup
Studebaker Champ
Jeep Comanche
Mercedes-Benz 300SL
Nash-Healey Hardtop
Triumph GT6
