There is a high-poly model for Racer out there. Cockpit looks fine too (on first sight).
Here is a preview from the model in ZModeler:
You could try to get in contact with the author and ask for permission to use his car model
Converting would be pretty easy
Judging from the mesh and the day it was released etc, this seems to be a scratchmade car! So there should be no problems with converting - but we should wait on what the author says
Information about the author can be found here
, the car can be downloaded here
Good luck with this! =)
