HELP!!! me pick out a car

Ok here is my deal, I'm selling my younger bro my truck and I'm looking to buy a used car only a few years old. I’m 23 so I want something kind of sporty either a 2 or 4 seater. I do not want to spend more than $18,000. I want a sun roof or convertible and its going to be my daily driver. I need all the help I can get I don’t know what’s out there to chose from. Any help I can get will be greatly appreciated.
Thanks

If you can handle a maual transmission, I would go with a Honda S2000. Not only is it sporty, but it has decent gas miledge and handles like butter. For the money, Go with S2000. Its a convertible two seater. You can easily get a used one for 18k.
