The 75 and ZT club has purchased direct from MG the earliest registered Rover 75 (S525 OVP) it was used for over 10 years as the Longbridge security car.
Its replacement it the ZS it the picture. Its the last ever registered MG ZS and has the G Series Diesel Engine under the bonnet (the G series was being designed to replace the L series Diesel in the ZR and ZS)
This was an unregistered MGR test car when they went bust it also has a completely different IPK to any other ZS.
I thought it might be of intrest.
