This summary shows the number of ZT 260s and Rover 75V8s known to have been sold per month since 31 December 2017.
Only UK sales are taken into account and the data is taken from the Annual 'Complete List of 260s SOLD' and the 'Monthly Ins-and-Outs' threads, updated daily over the period. I hope you find it interesting.
