I don't think the 75 had the credit that it deserved.
Mine was an 04 estate so quite a late model and was chipped for 170 bhp. I picked it up for a song when it was 2 years old and the value of them had plummeted due to Rover going toes up. IIRC it had 40 ISH k on the clock so I put 200k on it myself. During that time it had 2 alternators , a turbo charger and an air con condenser, other than that all other things were consumables (brakes etc). Never had a Z and I am sorry I didn't. 😳.
Replaced it with my current XF estate and strangely enough was thinking about the 75 this morning and how good it was in heavy snow. I had left the snow mode on in the XF and it reminded me of the 75, that was by no means a slouch, but of course the XF has 100 more gee gees.
