Had an SE6 about 20 years ago as always liked them (SE6 is the later model to the SE5 in the photos. Scimitar the did the "hot cross bun" add-in to make it wider and longer) .
SE6 has more space, but not as pretty as the SE5. Both ran the Ford Essex V6, and they drank fuel..... It did have a big tank, but even in back then, folk in petrol stations used to comment on how much it cost to top up!!
Scimitar bodies (fibreglass) can unbolt form the chassis, which makes fixing (welding) the outriggers a bit more safe. Front trunnions wear, engines an overheat as they need a header tank mod done to allow the coolant filler cap be raised (to prevent air traps). There is some load space in the rear, but only the glass hinges up, so watch your head on the edge when loading as there's a large stepped edge to get things over.

Window rubbers can age, fibreglass can craze (but doesn't rust!), door can drop on hinges.
The earlier SE4 saloons are now rare, and in my view a head turner. SE4a has a straight 6 Ford, SE4b has V6, then the SE4c had another straight 6.
