1988 Toyota Supra Turbo 36K How much it's worth?

[sssteve04]

Hi there want to sell my 1988 Toyota Supra Turbo 5spd 36K original 2nd owner, I bought it with 20K 10 years ago, always garaged 98% (orignal owner also) of it’s life the other 2% was spent driving it. Hardly ever in the rain unless caught out or even sun for that matter. Never scratched dented or dinged or curb rash on rims. Just took the orig tires off the car due to dry rot still had 50% tread. All of the miles are High Way. Car is Black with gray leather and all options expect targa. Some other upgrades have been tastfully added such as a boost controler and BOV and boost gauge.
How much do you think I can ask? it's very rare in this condition
Thanks!!
