Cant really help you but what is it with engineers reports these days on car insurance? Cant put a fucking air freshener in a car without them wanting an engineers report. Besides how will an engineers report be able to value a car, surely they are better off talking to a classic car club or an auctioneer who deals with classic cars? As for other insurance companies have you tried need2insure? People were raving about them not so long ago on here, could be worth a try?
