Allow me to correct the subject line!
I had a good look at the photos and description of the 4 seater after a friend (on here) pointed it out to me last week.
That brake overhaul was rather expensive (OTT!). With the description of chassis rot etc I would expect parts , if not the whole, body frame would require replacement.
Realistically the car is way over priced, but I expect if someone wants a long term project, they may find it attractive.
At the end of the day, it will cost far more than the car will actually be worth once completed (as with most such restorations).
