We can never value an individual car, but obviously a one-owner 41,000 car should be desirable - especially if it's in good condition with full history, running well and has a current MoT. Prices cover a wide spectrum, with MoT'd projects going for as little as £500 while 'time warp' models have been spotted in the classifieds for more than £5000 (although whether they sell for this is impossible to know). The best thing to do is try and find a similar model for sale and price your car accordingly.
