Why not keep the Astra until it fails an MOT? Buying second hand is always gonna be gamble, might get a 20k mile car that's shagged from doing short town journeys or a 100k motorway cruiser that's asked for nothing (or vice versa).
I reckon the next MOT is the one where it might fail, so I’d rather spend some time saving and researching my options. Can’t be without a vehicle for work and I’d like to avoid finance where possible. Very much just speculating at the moment (and who doesn’t like window shopping for cars?).
