I didn’t have a clue so just spent £15 minutes doing a quick tally up.
Car:
Loan £0 (Paid off, had it years, big mileage)
Fuel for 21,000 miles £2550
Insurance £250
Breakdown Insurance £70
Garage costs £40 (just the MOT)
Tyres £200 (averaged over life expectancy)
DIY costs:
Brakes £80
Major service inc gearbox/coolant £115
Suspension bits (proactive maintenance) £180
£3485 or 16.5ppm
Camper:
Loan £0 (had it a few years, bought with savings)
Fuel for 4,500 miles £980 (MPG dented by lots of towing)
Insurance £335
Breakdown Insurance £70
Garage costs £35 (just the MOT)
Tyres £100 (averaged over life expectancy)
DIY costs:
Rear discs, pads and one seized caliper £500 (result of overheating)
Major service inc gearbox, diff, coolant £160
£2180 or 48.4ppm
Combined £5665 or 22.2ppm. Admittedly, I have probably spent loads on tools and lost days spannering instead of cycling…
PS Depreciation, the car is negligable as its 10 years old and the mileage means it would only really be bought as a bangernomics car by the next owner. The camper, must be depreciating a bit but not considerable, cos its a camper.
PPS Forgot the road tax. Car must be £200ish, van £230ish.
