Oh, that's good news. Sometimes, the "hardly driven by an old person" cars can, as z22se examples, be encrusted internally by some scrooge who deliberately ignores the "whichever comes sooner" phrase in the maintenance booklet. Looks like your previous wasn't one of those owners. The two things that garages (dealerships, which is a good thing when someone else is paying, do tend to profitably tick all the boxes on the page) is the cabin filter and (see later) tyre age, as opposed to condition.
The cabin filter is a DIY change (much easier for me with a LHD, the battery cable gets in the way on the RHD) and is also easy to inspect. A filthy one doesn't harm the running (so indies often never look) but it makes the car fusty.
1NELIFE is a (rhd) C owner and member on the forum, some YT vids are for the lhd. If it's as grey and nasty as the video one, then replace (only a few quid on ebay).
The garage could well be happy with the tyres: they check for tread depth and cracks in the sidewalls which would make them unsafe. However, the rubber deteriorates with age (more so if standing unused funnily enough, the rotation and warming/cooling cycles from driving keeps them nice and squidgy). I'm a science nerd and found research that shows several metres of braking distance are added on to old rubber. Pre-2015 tyres, I'd bear that in mind; pre-2010 tyres I'd be inclined to replace for my every day driving.
I'll point you to some mirror options. Front bumpers are often worthless. If I see one in Herts, whatever the colour and condition, it might be worth getting just for the V alone and throw the rest in the hard plastics recycler at your local. If a Space Green appears (I do see them) then even better for future keeps.

looks like yours and the VIN plate is by the air filter on the front suspension turret on the driver's side. Click on the pic and you can see "588"; the code for Space Green. Hopefully, yours is the same code but let me know or upload a pic.
