HA, Paul, you sound like my brother from another mother! I bought my CMC kit new in Nov 1988 - had it shipped to N VA and worked seriously on it for some time. Got remarried, had a kid, bought Chesapeake Bay property for retirement, retired from DOD and took Wash DC consulting job so progress halted and it became covered with stuff in garage. I paid $9k for deluxe classic black (supposed extra cost) gel coat kit. I added a '71 VW chassis that had been my new wife's car when she attended college in FL. Retired totally and moved to NW FL - thinking I'd get back on building it - needs another 40 hours for wiring and upholstery. Adding up my receipts I come close to $14k invested. Engine rebuilt 1641 cc with CW crank, 110 cam, new 043 heads, dual Dellortos - but never run. Mine has sat so long I might have to tear apart and put it back together. Already been through 2 sets of unused tires due to age! And 4 sets of wheels due to my changing taste - 4 lug VW/chromes/Pedrini/2L Fuchs --- and eying 5 bolt Fuchs replicas now.
@Alan Merklin says the flared bodies are not as sought after as the classic bodies although I think they were $1k more in 1990. So perhaps $1-2K less valuable.
Parts are becoming expensive - some of the original CMC parts aren't worth using today (like vinyl top/tonneau and interior). A VW pan with trans and core engine with title seems to be $1500 not and perhaps a tube chassis would be better.
I've seen forgotten kits go for $2k years ago - none under $4-6k recently though. Think Alan said it easily $16k to get one nice and on the road - and that was a couple years ago! So maybe taking a 50% loss on new cost - would net you $5k. I haven't bought or sold one - I'd sell mine but so close to finishing I hate to admit defeat!
So how far south are you headed? Retirement? I went from DC are to FL - to avoid state inome tax, lower cost of living, less people and wife's aging dad (now deceased).
