I have a car, it's just cost me over £200 for MOT, was more than that last years MOT, have also replaced the clutch, new window when it got smashed, etc. Today the driver's window is jammed, I need a new window regulator and am looking at £220 new part, or £120 second hand part. I've had to ask him to jam the window shut for now while I save to have it repaired. 
I have always just had a cheap run around kind of car. Cant afford a car on finance or upfront unless its £1000 or under so I'm aware it will likely need more upkeep than a newer car would.
My mechanic has said car will likely need a fair bit of body work doing come next MOT.
I need a car. DS has special needs, goes to a paediatrician out of county and soon will be starting a school out of county where I won't be doing school runs but would need to drive there if he was ill or there was an emergency, and for termly meetings, open events, etc. DS has his sen and DP has cerebral palsy. Baby on the way too.
I'm not working at the moment (due to DS being out of school) so money is tight.
I just don' t know when do I cut my losses with this car, sell it and get another? And then how do I know the next one I buy isn't a money pit? This is only my second car as I didn't pass my test until I was 30. I've no big brother, dad, etc to ask car advice of, and DP doesn't drive and has zero knowledge of cars. I need sage car advice!
