For a FIRST turbo car, I wouldn't recommend something that already heavily modded, as starting with less kw and doing the mods yourself will teach you so much. Such as how to handle it and how to repair it. Also it heaps of fun to learn about the mods as you go.
At your price range whatever you choose will need money spent on it, so get something you can learn and experiment with, but ultimately YOU have to like it.
The cars mentioned above all have their merits and it really is personal choice. if you can, do the rounds, sit in each one, drive them if you can, and find one that feels comfortable and has the styling that you like.
