As a note, Chris I wonder if the configuration of the black car is a bit too radical for a rental. For a rental you want it to be reliable (as 911 pointed) and then you want it to be reliable. It might make more sense to put a stock 3.0 in there and save the good engine as a back-up for your car.

That will both reduce the value of the car and engine (in case of damage by the rental driver) and in an accident. Body work is body work and as long as it is solid and looks good from 20-30 feet it's fine. This is where fenders held on by Zuez fastners is a good thing. To be honest you almost need to configure the car as a rental from the get-go. Another detail is the drivers seat. In your own car you might bolt it to the floor for the strongest mount and the lowest center of gravity. In a rental it's much better to have it mounted on runners for easy adjustment to the driver's size.
