I just love driving and quite often take myself out and around the Cotswolds, just for the hell of it! Can be gone for a couple of hours at a time, glorious countryside, great roads.
Can't be that far from you in Oxfordshire? If one loves driving one doesn't need a reason to go out.
If the car isn't costing you, just to have it sat at home, then hang on a while maybe your enthusiasm will return?
