Ive seen worse had a guy bring his z4 in for an mot all his run flats were corded one with bands showing the rears had 4 inch holes in them and all his brakes were past metal to metal, you know the pad was completely gone and it was pretty much just the caliper piston sqeezing the disc. and only 1 external bulb worked. the hand brake didnt work and the wipers had torn off so it was just a slither of rubber scratching the screen. iirc it required a grands worth of tures and the same agin in brakes. but the brazilian drug dealer refused to get it fixed, and took it away, we were seriously considering calling the police, because it was such a shed. but it was game over when he decided to floor it out of the dealers, but the tyres were so fuct it spun a rear one off the rim and hit a kerb and broke his front suspension spring, but he still tried to drive it off.
but the cases of just shear ignorance in regards to vehicle maintenance i see daily really scares me i had a guy who hadn't serviced his car in 40k when asked why, his response was he never got a reminder through from his supplying dealer. he could not understand what a duty of care was and how ultimatley the maintenance of his vehicle is up to him.
