My 1st one reached 2 years old in March.
It was a Pure SD4 manual and with some nice extras it was £32k (ish) new
I chopped it in and I know it sold from the dealer for £28K screen price in little over 2 weeks.
100% reliable from a running point of view but interior light needed a service bulletin modification and had the rear lenses replaced due to excessive misting up. I say excessive as a minimal amount is considered normal under certain atmospheric conditions and clears quickly.
Xenons lights are highly rated in comparison to the halogens.
Spare wheel.
That would be my base level.
Anything extra would be ...well read the spec in my signature.
You'll know whether privacy glass is a must when you see potential cars but after market wraps would be a close substitute obviously.
The manual is more economical than the 6 speed auto but I have found the 9 speed auto better than the manual.
Saggy Seats have been reported a lot but I'm sure that in years to come it will simply be one of those things as the main gripe is that they shouldn't go like that from new. Mine were/are OK but there are differing levels of acceptance as to what is normal.
Rattles and squeaks have also frustrated some owners and of course it all gets reported on these forums so it may be less prevelant than you think. Again mine are OK ...go figure.
A long test drive is what you want covering motorway and round town.
Find some road humps and go slow and faster over them for suspension noises. Squeaky bushes have been reported.
Try all the steering wheel controls.
I think the 5 yr service pack that many have paid for stays with the cars so thats worth checking out...3 years left on a 2 year old car.
The early ones had a parcel shelf that was a bit big and rubbed the black paint off the tail gate pillars leaving white plastic showing through. Again a bulletin was issued and the pillars were repaired and parcel shelf should have been replaced if there were issues.
Oh and finally...
It would seem the boot shrinks after you buy it so be careful of that
