why the specs? why would the kind of person looking to rent a car need a specced 14 to learn the basics of skidding or not?
outlay is too high for what needs to be a cut spring, weldered S12/E30 or the like for reliable douhnut pens newby basics.
300 quid motor, 300 mods (wand, seat) and 40-50 full day charge with 5er per 15inch tyre you will never get through. Bit like the driftskool ones but with a bit more thought on the set up and instruction
edit: the only people needing more than that will want to save money getting there own cars sorted
