Good point on the collation of what to look for items
I'll have a think about it
Key ones to be honest are
Has the fuel filter clip (orange clip) been done
Has the heater hose been replaced with the uprated on available from the club
Look for scrubbing on the tyres, may indicate alignment issues, many places set them up as standard ZT's - but set up is different
See if you can see any mention of diff/gearbox oil changes in the service history, depends on age of course
Take a look at the state of the rear discs, we have them available through the club and less that 50% of Xparts £700 a pair bit it's still a fair chunk if money
Have a look and see if the engine undertray is in place, helps cooling and hard to replace
Not specific to the V8 but look for indications of leaks - water in boot, damp carpets in footwells
I'm sure others will be along with more
