Cars come and go, so does money, the question is who you share your time with: With a vintage car you share your time under the bonnet and with crusty old men at classic car meetings. With money you share your time with leeches and people who think you are worthy because you have money.
I'd rather spend my time with bohemian vagabonds, the spirit of my life doesnt need a vintage car or money. So keep the car, stuff the money, and get a life worth living.
Oh, nice car btw, it's quirky and stylish I like it. Sod owning one though, cars like that need too much work to keep on the road.
