i would go s2000 bc that is more of a car of youth. A lot of people say that slk is a pussy car but i will tell you me and my friend had our fair share of fun in his dads back in the day. Was an 02 kompressor 4cyl supercharged. That thing would move, the system pounded from the factory and it was just a nice car overall. S2000 i have never ridden in or driven but i am looking into one myself in the not to distant future.
