Okay, so this is starting to make a little more sense. Please correct me if I'm wrong.
You feel your project car is worth $48K (with over $50K invested)
He feels his turn key Hemi clone is worth $60K "Buy it now" ....Drive it now....
He contacted you about making a trade for your car plus you give him some cash.
I'm assuming he wants you to add more then the difference of $12K cash ?
I think the question(s) you have to ask yourself are:
#1 Is his car currently worth the $60K asking price ?
(My opinion...YES)#2 What would the current value of a "U" code auto be fully restored ?
(My opinion....$75K-$80K tops)#3 On top of your $50K currently invested, how much extra would it cost to restore your car to a level where you could sell it for top dollar ?
(My opinion....another $60K minimum)#4 How much are you willing to spend to get a turn key driving car ?
If you spend the money to restore your car, (I'd be glad to do it for you
) You will have over $110K invested in a car worth $80K....$30K loss, but a real nice fully restored new rare original car.
If you give him say, $25K difference, you'll have $75K invested in a $60K car, only a $15K loss, but it would be a cool HEMI 4spd Shaker car
In hindsight, I think you never should have taking your car apart if you couldn't follow through. If your car was a turn key driver, you might get a better dollar, but as a rusted out, blown apart project, I think you'll have a hard time "A" finding a buyer and "B" getting anything over $20K.
I know it sounds insulting, but it's true.
