I'm sure many people said that about minis, escorts, cortinas and Sierras etc... It is amazing what people are prepared to pay for what I guess is nost***ia?
S bodies aren't that bad actually they're arguably quite good and so that could be being reflected in the upshift in prices maybe...i was reading the other day one of the biggest movers in the hagerty classic car index had the Austin Allegro as one of strongest performers in price recently.... A truly awful car.... I used to ask my mum to drop me off round the corner from school rather than take the abuse from friends by arriving in that monstrosity!
It'll take time for all the shit boxes to rot get repaired or exported before things really get interesting.... For now I must admit I do struggle with the price of cars like (just looks rough);
