Italeri's Porsche Turbo, which is getting kind of old now.
I did get a R8 recently, but haven't busted into it yet.
And I just picked up the New Revel Nova.
I am getting in the mood for armor though and have been looked at the Cyber Hobby Tiger, which is just an amazing kit.
It is a limited one run kit and the LHS happens to have one - I'd be in the dog house though if I sprung for a $60 armor kit.
