I have done exhausts in the past. One on a 13 year old 1990 Hyundai Pony and one on a 15 year old 1997 Polo. I've not had an exhaust on anything modern. Well... We had a clamp come loose on the Punto but the garage fixed it FOC and simply asked that I put a couple of quid in the charity box. As for the others...Well for one you just have a lot more "sundries" which need wear and tear replacement......... Have you never needed to replace an exhaust, radiator, cambelt, clutch, oil/filters, ...... ok brake disks and pads can go on an EV, but not as much (i drive entire journeys without touching the brakes and indeed have to force myself to use them properly once a week just to make sure they do not seize - one of the many anti EV complaints which triggers me about their increased brake dust )
a lot of this depends on how lucky you are or how long you keep your car but i have had all the above fail / have to be replaced as part of good maintenance on my cars, along with DPF (that was a pig), blown turbo (that actually was what made me get shut of my 2nd fiat coupe) and a new gear box in 1 car, tho part of me thinks the garage swindled me there!!!)
to be balanced, an EV can have a range of charging faults that you wont get on an ice.... the battery could fail but that is under long term warranty so not something i need to think about for a good few years yet.
Now i have said all that you can be certain i am going to have an electrical fault in one of our cars...... probably the I3 as that is the one not under warranty
Radiator - no
Cambelt - yes, preventatively as per the service schedule.
Clutch - only once at 114k on a remapped car that got driven hard.
Oil / Filters - obviously
Brake discs and pads - now this is an interesting one. My company car is on original pads and discs at 76k. We had to do the discs and pads on the wife's car at 22k due to corrosion through lack of use. Or in other words, I haven't really worn them out very often.
The people I find have the issues with cars are those driving premium or performance cars. The run of the mill stuff is so reliable currently that I really don't see it as a positive/negative argument for EVs either way.
Sure, servicing should be cheaper but everything chassis related (shocks, springs, bushes etc..) are on parity and I think it's probably fair to say you'll be spending more on tyres in an EV.
