But...but.. are we talking of that beauty u and your son are finishing???.
Damn it Bill..DO NOT SELL it...just maybe keep it apart for a period..but PLZ dont!!
Maybe in some year the son can be even more helpful...will be a big shame for all sell that after all THAT amount of work.
Money and time is really often a big problem in such passion (and here is talking a nut living alone ...but with 3 cars,loving all bmws, cobras,gt40, old porsches...and not even happy with a shop full of smaller ones..)
PLZ save the 40..
