Reviews and specs aside, the S2000 is a pretty quick car. Raced one a while back at the old Wesbank raceway with my Astra OPC H, we launched together I held him of in 1st and 2nd but he came past me in 3rd at a rate of knots. Spoke to the owner of the S2000, said the car was worked but did not give any details.
My OPC was one of the stronger stock one's did something like 157kw @ wheels. No contest from e46/e90 330i/D, also edged slightly tweaked 130i's at the reef, runs up to and passing 250km/h.
S2000 is a screamer with decent performance.
