Went to see a Morris Minor for a fellow message board member today.
Car was sadly rather rotten (repairable)
In the barn there I spotted the following:

It's a 1973 Humber Sceptre Mk3 with 1725cc Rootes lump (with overdrive etc)
I managed to get some photo's of the interior and the underside:


Interior


It's not been on the road (officially) for "a while" and is thought to have done less than 12k miles.
The only rust I have found is on one of the doors, there are some superficial bubbles on the rear door.
Any idea how much it would be worth?
I know the asking price, it's not a lot... (150 quid before haggling)
