Not even close with it being nat asp. You want something that comes with a turbo as standard at 10k you should. E looking at Subarus or R32/33 skyline gts A lot of good VAG stuff in that price range too.
With Supras and GTR Skylines probably gone above the 10k mark now, I would say RX-7 is the one to go for.. Assuming the 10k is just for the car and not modifying also
