personally i wouldnt bother(again!)
If you really want one get one that is already running and driving.
Parts supply is non existent from the club or anywhere else(unless you have a Minicar they aren't bothered,and i found getting hold of imp related parts a chore,took me over a month to get a set of radiator hoses.)
They are also appaulingly made,made my Robin seem like a luxury car in comparison.I dont usually say this about any car,but how Bond got away with not only making them but being allowed to sell them for use on the road is beyond me.
When Reliant bought Bond,Reliant's managing director instructed the engineering department to take a mk2 875 around the Mira test track ad report back,the tester literally walked into the managers office and strongly advised that he end production immediately,for all the reasons that are well known regarding their "handling"
As to not rotting away,dont believe it!a friend of mine has one that was on the Isle of Wight for 20 years,anything metal has rotted away,yes there isnt that much metal parts on them,but all that is there is unique to them and impossible to find.
