Firstly what a well specced, minded car.
Unfortunately the value of something is only what someone is willing to pay, which by the sounds of it doesn't come close to the emotional (not to mention the financial) attachment with the car so money is only part of your decision. With that taken taken in to account my advise would be put it into storage for a while if you miss it keep it (I would anyway) if not cut it loose an move on.
For some cold home truths bring it to a garage and see what they say on its value. Your probably not going to like what they say but that's what the industry values the vehicle at, as the two biggest drivers of a cars value is a number bolted on to the front an rear of a car and another displayed number on the dash. Both have nothing to do with a vehicles intrinsic value.
