I have a buddy who has a 99 Cobra and I have a 05 Gt. We use to race all the time and I would get him by a car or so. We have about the same racing exp.
With the 99 Cobra you have to make sure that it has the power fix. Which replaced the intake manifold and reflashed the ecu.
same here ive raced two cobras a 99 and a 01 beat both by a car, it was a close race each time but it really came down to drivers (not to gloat but im a better driver than my friends), id cast my vote with the 05 much more comfortable and better built.
