The annoying things are:
- you fail for seat adjustment! (I only noticed last week that the seat wasn't moving forward when I put my bag in the back - thought nothing of it)
- I never use my handbrake (am I alone?)
The worrying thing though is 'excessive corroding' (where does that stop!)
Not very good reading but only one to worry about really is the subframe rot, I had mine repaired for one MOT and then replaced the whole frame a year after.
Have a search ‘subframe’ and there are a few posts of similar issues so yu are not alone.
Pic of my old frame below, had a repair by the engine mount on the same side as the hole.
A pre purchase inspection might have been a worthwhile investment at the time you bought the car. Although there are things that get flagged up that are a nonsense ( like bonnet emblem badge deterioratied) and other stuff you cant judge ( brake line corroded ) and stuff they miss too ( wheel bearings), it does give you a feel for the car's potential to demand expensive attention....
That said, looking through previous MOT's can often elucidate further as to up"n coming issues too. But as I have eluded to, it only tells you what they know.
As the yanks defense bod pointed out once..there are knowns, there are unknowns...and there are known unknowns !
