Depends;
For starters, I'd recommend a Mazda MX-5, or something relatively low/medium power (250-300hp)
If you're familiar w/ drifting, then I'd either add power to a car that you're familiar with, or move on to something with downforce + more than 300-400 hp. The Sylvia RM is a good example.
If you're really good, then a TVR Speed 12 w/ ~900+ hp would make you happy
