Hello - welcome.
although the knowledge available on here sometimes makes you think some drove from the womb.
That is way out. You'll struggle to find a good RHD 260Z for less than £20k and a good 240Z is going to be closer to £30k. By 'good' I mean one needing no work but perhaps not concours.Cheers!
so I’m looking in Classic Car Mart from Feb 2021 and they say a price guide for a ‘good’ 260z is £7500.
That seems remarkably cheap as I can’t find any at that rate.
