Currently looking here too.
Our 15 yr Diesel Golf is on 150k miles snd we have to drive in that Ulez quite a lot - it’s got problems with the heating and coolant use so very much at the is it worth it time.
Had experience of Honda, Lexus, Skoda, VW and Audi dealers - some good, some meh.
It’s certainly a trying experience snd I quite like Cars.
Currently at the stage where we either
1 - run the Golf into the ground
2 - by something ULEZ compliant but doesn’t cost a huge amount 2ndhand
3 - buy something nice and new with a good warranty cos we’re worth it and fuggedabahtdit
Proper paralysis by analysis currently
