in low mileage all original 100% stock condition id say your correct.
if the car was a 1LE, firehawk, tta or any other extremely desirable 3rd gen i would put it to stock condition.

these cars arent like 60s/70s muscle cars yet where the price of an all original mint low mileage car is astronomical in value compared to a restoration.

in low mileage mint original condition my car would prob be worth 10k tops. in restored form the value is going to be less. in my situation i feel that the cars value in restored condition will probably be higher with the more modern drivetrain and other special work done to it.
