I have had a 914 project car for 20 years now. Accumulated a bunch of parts over the years with the intent of building a track car. Wanted a 2000 lb car with 400 hp from a NA flat six. Imagined how great it would be. But now at 50 years old with two kids under 5 it was time to realize I’m not going to finish it. So I sold all the parts and then sold the chassis to a guys in the US. Hate to see it go as it will be really cool when it’s finished but I will be better off buying a stock or slightly modified car in the future. At some point you have to be honest with yourself and critically evaluate the odds of finishing it.
