As Andy said, if you spend a fair bit on suspension you will improve it alot!! And becaus eyou can add a lot more power to a S2 you will be able to lap quick. however on the corners the 306 will aslways have the edge as its just awsome in the handling stakes!! the only other car to impress me like for an every day car was a Focus

i got a 306TD and have had so much fun in it! even with cheapeo tyers (£21)
