When I'm in the market for a used car I look for cars that have mods, as long as they are what I want that is, good quality parts is always a plus in my books, I don't pay any extra compared to a standard car though.
I would clean the hell out of it and put it up for whatever the similar mileage cars are going for.
As for the OFT and E85, I would drop back in the stock tune and run 98.
If a kid turns up offer the OFT as a freebie, if they are older, dont, I wouldn't touch a car that had a OFT, personal opinion.
Is it loud, that's gonna limit you buyers.
What brand are the wheels, Jap or no name lead weights.
Do you have the OEM parts or do you need to source them.
How much money can you make from selling the aftermarket parts, if you can even find a buyer for them.
Prices range from $19k down to $12k on car sales.

Mostly it depends on how willing you are to sell it, for a quick sale start at $13k, if you have the time, and if the car is mint, start at $18k and drop it by around $100 every week, even then it might not sell for months.
Anyways, have a look on carsales and try and rate your car to typical examples, and then drop at least $500.
Good luck
