i say sell it to him...its always fun building cars and in that sense you can let them go and do the process all over again and still have fun...plus didnt you say you wanted to do more with your life than mess with cars...i say go for a change and sell the car...plus if you get interested again you can always start another project later down the line...but if you love the car too much..i guess keep it

what do you want more? if you dont know, sit down and make a list about pros and cons to help you decide.
