Yes it's a blend of all those things. Currently I'm about to scrap an old Mk6 Civic with one owner as it's simply not worth saving when scrap will get me £180 for the car. It will need an MoT, CV joints and other bits which simply aren't worth doing.It's having the time and the equipment, and knowing its safe. If I could change the aircon rad myself that would save a lot and might be worth for resale value but I have no idea how I would get to it. Do you need some ramps to get underneath?
You'll need ramps to get under a mk8, even standard non sporty models are low. Air Con Condensers can be done yourself if the AC system is empty or you're a naughty person. It's just unbolting then replacing but there will be trim and random bolts that will be hard to reach. Plus no guarantee it's just the condenser either...Home mechanics is a can of worms and always seems to get deeper or throw spanners into the works!
