I used to crew for Rotary Performance in VA. If I recall correctly they rented their Spec RX-7s for $600-$700 for a comp school weekend. They were good cars for a while, but eventually were pretty beat up. RP started out doing rent-to-own, but then decided it was better just to rent. Under the rent-to-own scenario, typically they would apply the rental fee from a comp school towards the purchase price.
