Just spotted a rebuilt 250 MZ ISDT for sale on eBay. Seems a good 'un and the asking price of just under £5k may be a tad optimistic but, there again, it could be about right. Definitely a collector's item and probably a good investment as it looks in excellent condition. Seller description states that it runs well after its extensive rebuild and is UK road registered. Also it goes like a rocket! I had one of the later versions (orange and white) a few years back and I remember its lively response when given a handful. Great fun.
April '20. Another one (see below) has just turned up on eBay. It's apparently a minter with just 16kms on the speedo. Description states that it runs fine. Wish I could afford it. Price £7995
Nov '20. Another one (see below) has just landed on eBay. Looks a bit rough. £5500 seems a bit high.
Oct '21. This one (see below) went for £10900 after a last-minute bidding war on eBay. How much?!!!
