id say cars that compete with the s2k are:Miata,Z4,SLK,Boxter,Sky,Solstice,Elise....then guess u could throw in cars like the 350Z and RX-8....id take the RX-8 over a S2k anyday,and id deff take a MX-5 over the s2k.....i still think the Miata is the standard for the roadster market,and i think they still do it the best
