I'm not sure about "the rising cash value" bit though. A tidy, original, Series I is worth up to around £4,500 or so. A ratty old one with converted this, that and the other is still worth bugger all except as an MOT'd vehicle - somewhere between £500 and £1500. At least people have larely given up making triallers out of then though.
