MOT and tax will always be the same. Tyres are a long term investment but can be had cheap if you’re willing (hell you could go part-worn for about 10 quid a wheel) and the dash – well, depends exactly what is wrong with it but unless it’s a new new car where the dash is half the control hardware meaning the car is undrivable, what’s the issue? you just don’t like niggling faults and want a new one?
The car was on v plate, 180,000k miles, clutch has recently started playing up, the pedal had fallen off and been reattached, I believe the dash problem which is common on VW cars of the era, is that some of the soldered joints had failed. which meant intermitent clocks, i had pulled the fuse out a while ago which works for a while. at 180,000 due a new cam belt as well. The windscreen wipers needed stripping down again as the spindles corrode. The drivers seat mechanism was broken and held together with some cable crimps.
Oh and due to the cars age i was paying on the pre 2001 tax levels, so far more than a newer version of the same car.
So yes i could have fixed and sorted most things, but for the cost involved, i cut my loses.
Newer car less to insure, less to tax, less to fuel. but i have a monthly charge instead. And for now no niggles.
