Car appreciation... the aesthetics, the engineering, etc

Off the top of my head (and I don't know the cars, so take this with a pinch of salt):

• Timing, whether that's belts (change) or chains (check tensioners, guides)
  
• Fresh water pump
  
• Change coolant (hard not to when swapping the water pump)
  
• Pull oil filter, check the paper for swarf, plastic granules, random bolts etc
  
• Maybe change the oil pump if being super paranoid
  
• Change the oil, send it for analysis if being super paranoid
  
• Fresh spark plugs
  
• Air filters
  
• Cabin filter
  
• Change transmission oil/fluid
  
• Change diff-oil
  
• Check the brake fluid and change if it's old
  
• Pads and discs - are the discs rusty on the inside face?
  
• Get a laser alignment done, when the cars in the air check the bump stops, the shocks and springs
  
• And see if it's missing under-body plastic shields, metal heat shields, what state are the jacking points in?
  
• Gas struts for the boot and the bonnet, are they old and lazy? If so, change them (or put a stick in the boot to prop them open in cold weather)
  
• What's in the tool-kit? Replace missing tools
  
• Is the spare tyre rooted?
  
• How old are the tyres? Get a durometer and replace them all if they've hardened up as they'll be a menace otherwise
  
• Are the tyres cheap crap? If so, maybe bin them anyway and replace with decent rubber
  
• Air-con, get it checked, replace the buggered bits
  
• Clean the rad/s out if they fill up with crap on these cars (996's hoover megatons of crap into the rads)
  
• And on and on really
