A slightly belated reply to both posts.....
Firstly re the price and auction, as stated it includes the buyers premium, ie about £45k, and thats before vat is added to that, so the buyer pays another £9k on top. Sellers, at lower levels, typically pay up to 10% + vat, or 12%. You can roughly halve that at higher levels, and this of course has to be deducted from the hammer price, ie what the seller receives. So not bad for the auction house eh, with 17-20+ % overall.
AE01 is a special car, and was always going to be about double the value of a standard car, so its not indicative of the market generally. Having said that Aces and Cobras are premium cars and have been ever since I can remember. I couldn't possibly afford to go and buy one now, but £500 in 1969 was about right when a typical MG, TR or whatever was £300 - see, the premium was there even then!
Club and membership wise I can only agree re the future - I've been a member, apart from 2-3 years way back, for 49 years. Interestingly I sent some thoughts to Terry Webb about this, and copied a link to an article about what some other clubs are doing to prop up membership.
