So I would decide if you were doing this as a one-time thing or if you may rent it again. If you are thinking about renting to offset costs, think about it very carefully.
Our rental cars (actually all of our cars) have hour meters. We have procative maintenence schedules for EVERYTHING. Things that you REALLY want to be in excellent condition so that you don't have to worry about are:
- Hubs
- Pads
- Rotors
- Tires
Renters will flat spot tires. Have extras.
Renters will bang the car up. Have extra Fenders, CV joints, hubs, rotors, pads, wheels, a transmission, clutch, etc. You going to swap that stuff if it goes bad?
Collect a damage deposit. If your guy can't afford it, he can't afford to fix it.
Have a rev limiter. Have data. Have video. What you will end up with is proof if there is a dispute.
Figure out how many times you could rent this year. Total up costs for new hubs, brakes and tires. Then add in your REAL transport fees, food, lodging, racecar gas, post race maint, garage?, etc. Amortize where neccessary. Come up with your costs.
In the end, it aint cheap if you actually want to turn a profit. We charge a decent amount, offer 'extras' like data and insurance but in the end, it's basically a loss-leader. Most of our arrive and drive clients came through our rental program...and they did because it covers EVERYTHING, they are on-track 100% of the time and they saw how hard that was to do.
