TTRS or Supra?

Depends what you want, the supra is more of a drift machine while the ttrs is a rocket off the line and way nicer inside

Supra , longitudinal engine >>> transverse If you prefer AWD you could take a look at BMW M240i xdrive instead, can be tuned easily ( B58 engine, like Supra)

Camaro SS 1LE

The TTRS will hold value much better.

Personal experience, the TTRS is better to sit in and slightly more bearable for longer drives. The Supra is the better car overall, this includes maintenance. Toyota will still honor the 10 year warranty here so I’d take the risk on that over the Audi. If you’re looking to modify them for performance, I think the TTRS has more options but I don’t know enough about these platforms, sorry.
