Theyve been banger money for a very long time, a shame really. Its a phenomenon that only really affects the UK though. My TS which I reckon would be worth 1500-2k on a good day is worth nearer to 6k here in NL.
The best bet is to hang on to them until they start to acquire classic status, the providence is there. Just look at Ford Escorts (and even Sierras now) to see what I mean.
The banger boys will clear the 'gene pool' as it were and the ones that are left will be worth more. Just got to sit it out.
