Apart from a few exceptional ones, prices for GTs seem to be on the slide again now from where they were a couple of years back. I bought mine as a restoration project during Covid times, and paid a fair price for it on that basis, but back then mint, and even far from mint, examples were being advertised (and presumably selling) for £25-30k and upwards. I'm still tracking sale prices fairly closely (mostly so that I don't go too bonkers with spending on my own project
) - there was that insane barn find one that went for over £40k a few months back, but £15-20k seems to be the current bracket for good cars.
This very honest looking 1970 one went for £16450 recently for example (I think it had an estimate of only 4-5k!): https://www.swva.co....i-1275-gt-1970/ - I would have absolutely snapped it up at that price when I was looking for mine!
