I agree.
I'd add that the market is dropping to more realistic values now and the bubble seems to have burst on overinflated drunken lockdown disastrous purchases. They are however still out there... Just not selling from what I can see.
Frankly its impossible to value without seeing images and detail of the current condition. Even then, its dependent on location and multiple other factors.
Start by considering your end game budget and what it is worth restored. Deduct what the restoration will likely cost and look at what's left. That's what its probably worth these days and I suspect no more than £3,000 - £4,000 absolutely maximum unless its something very special and very original. I picked up a one owner with all paperwork 1965 88" original Station Wagon towards the end of lockdown which is absolutely original but needs a total restoration. I paid £2,000 for it... If this one of yours needs a new chassis and bulkhead, you are are looking at a £20k rebuild.
