Mirakledba, I think you may want something like a Civic, or a Corolla to begin with lol. Slow cars may be boring, but it's easy to control for newbies. New drivers, and powerful engines are something that don't mix well. Usually, new drivers can get into a accident pretty easily, so it's better to have something old, and used to scratch up, and dent to gain experience.
Not to mention, the costs of maintaining luxury cars, and the insurance and the costs to cover one at your age will be pretty high.
