I have a 91 965, 80k miles, guards red with cashmere, that the wife would prefer to turn into kitchen cabinets

. I've owned the car for almost 6 years.
I would say it's a very nice example. Probably 8.5/10. Previous owner won a big concours with this car. Engine has been somewhat modified by Imagine Auto (I can provide more details if they're important).
Wondering what kind of value range for this car in this economy. Any inputs are welcome. Note - the car is located in Northern California.
Thanks.
Frank
