Convertibles and Sport cars for bigger people?

[Zeke]

Ive been looking around online and purchasing a car in June i dont want a truck or an SUV really dont want a Station Wagon but my budgets kinda small i dont want to buy a used volvo v70 or something i want something sporty and a convertible hopefully i dont know why i guess its cause im young i want a fun reasonable car i usually buy light salvage vehicles as my cars so i shop around any ideas on sporty convertibles that a bigger guy like 300 pounds 5'11 can fit in and out easily i seen a porsche boxster i dont know though all ideas would be appreciated
