Going back to OP:
Make and model, dealership or franchise? Ford Fiesta or Jag? To compare it with a can of Castrol old way back youre is no apples with apples with putting a car into a garage, nevermind a dealership!
Without knowing anything that's not so bad for a basic service from a "dealer" depending where you live!! I calculated back and wouldn't be uhappy with that from the local dealerships I've used. Our local Toyota dealership did us not bad late last year with a replacement interior blower. Actually the cost was huge for a small Aygo, but the labour itself was relatively small -and nobody else would take it on!
Also, I believe you can exercise your right for a few years now not to go to a dealer and take it to an indie unless it's bound by contract. The law changed, much like you don't have to use ariel liquid in your washing machine to keep warranty but you can still get a valid stamp in the book? That said I won't buy a new car on principle and no reason to check that argument out!
I've had a few problems trying to get mine and faimly cars serviced and the odd thing fixed the last 6-12 months. Most places are just useless now, just want MOT's and pick problems but no offer of fixes -even our local garage won't fix things now and we've had good history with them for 40 years but no reason to go back. I'm fed up with mine, had a few bits done but the quality and effort is shocking -and each and every time it comes out wth the same rattle and MOT advisory it was put in to to fix about a steering link (about £12 of parts). I come out with a "free" brake, tyre and exhaust check every time though! I'm fed up trying to find a place to do it. The ONE garage I used to depend on was permanently shut last year but not had the chance to check if they opened up again since.
These days I've no inclination, tools or available space to fix things myself so it's factored in to the cost of budgeting on a "new" car purchase. In some of my performance cars I made sure I drained the oil before it went black. Usually every 6 months or 3,000 miles. I also changed clutches, cylinder heads, pumps, cooling, brakes and suspension. 2x Celica GT4's made me give that hobby up -rediculusly complicated to work on and expensive parts. No way or inclination to even think to do that again!
For dealerships. Pff, Arnold clark wanted £600 PLUS parts and VAT to service my old CL500 -Indi wanted about £200 if I supplied my own replacement performance air filter. Soon as I realised the "dealer" was Arnold Clark I couldn't get out quicker anyway. Land Rover in Inverness weren't so bad a while ago -they were the only place I could leave my freelander to get fixed for a month while I was offshore (local lndrover specialists wouldn't touch it), that said, no example there 1.8 Petrol and I got shot if it when the head gasket sounded like it was going again!
Cars, meh.
PS where my apartment is in France is about 1km away from Renault Technocentre and apparently head of electric vehicle tech. Loads of electric cars round there. I'd imagine they will still need brakes, tyres, bearings and other consmables (they must go through more brakes and tyres in France from my experience anyway LoL). Is it not true over here still a cheap electric car is the Nissan Leaf still? Only problem is you need to change the batteries by now? £1,500 for the car but about £6,000 for new batteries? I might be out of date on that.
