I know your feeling. Until recently, I had 5 boats,two jet skis, four trucks, one car, and one travel trailer. Bad thing is I have no garage or access to my back yard by car. My neighbors love me!
I used to love those little British cars, but I was a Triumph sort of guy. Sitting in a MGB felt like sitting in a bath tub. You shouldn't have any trouble selling that little gem with those miles. Matter of fact, I am looking for a TR6 again.
