Biushes, shocks, springs (known for snapping on Clios) and exhausts are all consumable parts that can deteriorate from 'still fine' to 'needs replacing' within the space of a year - I'm not sure that them all cropping up at the same time is 'little enough care' lol
They never crop up at the same time, you end up with that fail sheet because they crop up one by one and youre either not aware of them, or ignore them.
Exhaust major leak even my mum would hear and come saying "my cars broken"
Rear beam bushed dont just fail, they degrade a bit as a time and are advised time and again before failing. The MOT standard in the UK are so slack it's untrue. By the time bushes fail the suspension is literally hanging off the car.
Shocks leak, sure. Again though, not instantly.
Springs I'll give you, they happen to the best of us.
What that fail sheet tells me is that no one has looked under the back of the car for a few months at best, or the last MOT at worst and have been driving it around listening to the exhaust blowing for weeks or months
Lets face it, it's unlikely its an enthusiast owned minter with perfect paintwork and recent belts that would sell for £2500 once fixed, it's vastly more likely to be a slightly leggy car thats coming due for belts in either 2 years or some miles, and even once you fix the fail issues, still needs TLC and will sell for £1000 as a project.
