Any info/history on #003?

... Ideally I'd like a trophy blue v8 with a super charger ...

There are two supercharged 260s known to exist in that colour, but I think both are "spoken for". There are several in Ignition Blue and a couple in Chagall, but none are known to be for sale at the mo. There is however a Royal Blue supercharged ZT-T for sale currently. Check out post #18 in the Complete List here: https://www.two-sixties.co.uk/mgoc26...-260s-FOR-SALE

... Dumb question, but when do the belts need changing on these v8s? And is it expensive?

260's don't have cambelts, but chains which last at least 150k miles.
Clutches can be expensive, being an engine out job really. A noisy diff can point to an expensive problem (£1k-ish). Rear subframe and front struts, rot in both cases, are also known to be (commonly needed) expensive items.

How about non super charged trophy blue v8 mk1s?

How about non super charged trophy blue v8 mk1s?

Well, just look in the Complete List I posted for you. Post #16 in the thread (VIN #057) should fit the bill?
Only 14 Mk1 ZT's and 1 Mk1 ZT-T in total were ever made in Trophy Blue (all RHD), so chances are pretty slim of others coming on the market.

That list is updated several times a day, so you just can keep looking there. It's pretty complete too.
