dollar for dollar it might not be bad....rent it at the $100 price (minus multiple day & aaa discount - say $90). After the 6-9 months or so, they sell it you as they do all used renatals (16k) and there you go a unique ride.
The math = ($90 x 30) x 7 + 16,000 = 34k - remember its a gt u had from day one and cosidering there is a 15k plus mark up on the gt500 its a fair compromise. Then rental fees can be wriiten off and im sure there is more to it too but i do have work to do....411...Hertz coproate hq...LOL
