Thanks for all replys, sorry i should have been a bit more specific (its the newbie in me lol). I have just started going to Great Barr slot car on a saturday with my daughters (cant make any other days due to work) and they run a standard class consisting of mainly mustangs, camaros and le mans type cars. I was just wondering if there is a big differance in makes in relation to speed and handling. I think for the time being I will stick with what works there and learn a bit more before I start tinkering. I will also be doing a "little" collecting of cars that I like and also have a small track at home that I can run/practice on.
