Hey Mike,
I would completely dissagree with the statement that you can't tinker and tune the Delphi. I have one and it performs great! you can tune the car up if you want to and if you want to refine the car down to where u want it for road coarses, or for oval tracks, the Delphi can be tuned for whatever u want. withe the Type B tyima tires the car really handles the road well! and can be raced as easy as any other touring car you can put against it!
