 This is NOT a sports car.  It is a "sporty" two-sedan.    The manual transmission is very disappointing. The car corners well, but is not very quick 0-60 mpg.  However, it does well getting on the freeway (30-70mph) It does not compare very favorably to a 911 Porsche, but it competes well with the SL 500 Mercedes.
