Consider this; E&E
Emotion -vs- Economics
"friend is nagging"
A lot of guys here might flame me for this but, & I know we are not placing puppies for a good home here, but since your first option is not testing the open market for economic maximization then consider the likely hood of the "FRIENDs" intentions to own and finish and enjoy the Car, i.e. the good charity and benefit to him and the hobby (Giving him first chance and untested pricing i.e.. auctions) -vs- the chance of a well bought quick flip by the potential new owner.
This is in relation to the pricing gap you and he have already placed a sales value on this car, unless this gap is huge the above could temper your decision to sell to the Nagging Friend -vs- getting it out on the market.
"I’ve intended to build the car for years but the reality is I have more cars to build than I have years in which to do it
. For the right price I’d lighten the load."
This is a familiar reality and the fact you recognize it is HUGE, We only have so much time here to pursue these toys,,,,,
It is like a first step in "PROGRAM!" -- joke,,,,,"!"
Get some pics we are foaming
