I had one just like that back in 1992, and it was in far better nick than that one, yes I know that was 26 years ago!
But, as a "classic" looking for £3K+, the engine bay is filthy, the interior with replacement radio, scratches across ash tray, and badly damaged storage nets behind front seat, polished out rear badges, and I think I can see evidence of 'bubbling' around the wheel arches that are so familiar to me (that is why I parted company with mine in 1997!)makes me think no way we I pay even £500 for that, let alone £3K+.
Front looks good, but thereafter not good at all!! I wonder what a look underneath would reveal!
Just had another look and i,ve got the same unit in my Desmond. Quite pleased with it to be fair. Listening to Genesis on the way home from Mums this morning and sounded great through the original speakers.
