I sold a car I had for 25 years and built 90% of it. Everyone thought I would never sell it. I did and was able to get something else that I enjoy even more.
Time changes things.
I sold my Challenger to get another BAE bullet for my race car. I thought that I would regret selling but after 3 weeks I still see it as a positive. I owned it for 17 years and did everything but the last paint job myself.
