Interesting, looks like quite a bit of work, you could be looking at $40,000-$60,000 for a full restoration. Just done my Aceca, doing my Ace at the moment, the paint is shot on this car, plus all the suspension looks like it could do with a clean.
Lower sills look bad as well, price is too much for me, getting close to Cobra country when you include the rebuild cost!.
It may just be were the market is going on the other had, you will struggle to get a good ac bristol in the UK for less than $160-170K, a race one fully restored up at the $270-300K with full history.
Last point the engine seems to be from a few sources!, interesting.
