To add to Neilda's comment the running cost of the larger cars is becoming a LOT more expensive as garages continue to increase their per hour labour charge on ICE cars and they become more complex as they hit EU6 emissions capability? A big lump like my ML63 and a Range Rover eat brakes and tyres etc so I expect the re-gen and lack of moving parts should make a heck of a difference when you multiple the work by hourly charge for servicing. This will continue to increase as the car dealerchains come under pressure through the squeeze ahead.
I still think the more valuable thing is to reduce travel as far as possible (for work) in order to drop all costs. Petrol, servicing, road charges (soon), insurance, tyres, speeding tickets (oops) and ginsters at the petrol stop.
This is why I tend to do all my own servicing/maintenance. Recently changed the fanbelt on the Corsa. Due to transverse layout, the airbox, engine mount, wheel and inner arch had to be removed. Around 3hrs hours work for a £13 part - garage bill would have been nearer £150. Did the brakes/pads/discs and DIY was under £55.
Unfortunately location of work means less travel is not an option, and local transport services are infrequent and expensive.
