Condolences also , just been down that road myself.
I would think that a big issue with the car is that if it has an MOT or not? Not the end of the world though !
In the picture it looks good & I would guess by the the background that it probably lived in a garage when not in use. The valuation that Chris lewis has posted could well be correct with the details you have given so far. This forum is not like the Bull Pit of eBay so I would say do not rush into a deal , give as much detail as you can about the car and see who comes forward , believe me there are people out there that will love this car [-/
Also a few guys looking to make a fast Buck
