I do a good deal of my own work also. Realistically though, not everyone is mechanically inclined. It's not just a matter of choice; they simply don't have the skills to do their own work. For them, those extra maintenance costs are very real. As cars get more modern with more onboard electronics controlling the mechanics, I too am becoming more dependent on professional assistance. Being retired military I still have access to the Base auto hobby shop and can get free advise there often (as well as cheap access to a vehicle lift and heavy shop tools) But again, not everyone has that priveledge.
I can understand that.
With the folks i have in mind if they approached a car with a bucket and sponge i'd want the immediate area evacuated, never mind a spanner and socket set
There are also those folks driving premium cars, although i did 99% of the work on my 911 myself i still had it serviced at a reputable specialist garage, as selling it on without a FSH would have been a nightmare and i'd have lost more than the services cost.
Then there are modern car EMS systems, all of which will need the service indicator reset and any OBD faults read and diagnosed.
If money was a major concern though (which i conclude it must be as these folks were sat in front of me moaning about it), then you'd think they'd at least be bothered enough to ring around and get a few quotes, rather than go straight to the main dealer.
A while back i was sat listening as the old gal told me how much her car cost her to run and the expenses she's had over the last year.
So i told her to itemise the expenses (as it was a new car so it shouldn't be THAT bad).
Turns out she took her car to the main dealer to get her tyres and exhaust changed
She dug out the bill and she paid out £800 for the exhaust and £600 for 4 tyres.
To prove a point the next time were out i stopped off at the local ATS type place that i knew the main dealer used.
The exhaust was £350 fitted and the tyres £200 fitted and yes they had fitted both the exhaust and tyres to her car.
So that's near on £1000 she's paid to the main dealer just because she couldn't be bothered to ring round anywhere else.
She THEN sold the car a few weeks after
Even crazier is when we were last back over, she sat moaning about the exact same thing, turns she did exactly the same when her new cars tyres needed replacing
So motoring can be as cheap or as expensive as you make it.
If saving money is a major priority then go out and buy a used VW Polo bluemotion diesel, it'll sip fuel so slowly you'll have forgotten how to fill by the time it next needs more fuel
Buy it private and look around for a good deal, service it yourself or ring around some smaller garages and get some quotes.
It's diesel so the motor will still be running long after your grandkids have grey hair, just look after the shell and it'll last longer than many of us on here.
Regarding used vehicles; well that's partly true; if it's for a second vehicle or a hobby vehicle. If you seriously "need" a vehicle though it's probably imperative that it be absolutely reliable. Meaning that when I get in and turn the key it absolutely must start; no dallying around under the bonnet while the wife is sitting in the passenger seat screaming to get to the hospital maternity ward 20 miles away in town. Not such a big deal if you own 2 or more vehicles, or if it's more for convenience than necessity.
I'm sorry but there is no car or mechanical/electrical device on the planet that's 100% reliable, age and value makes absolutely no difference at all.
Speaking as someone that has been repairing, tuning, buying and selling being in or very close to the trade and driving pretty much all types of cars from £30 bangers to Ferrari's, Porsche's, classics etc for the last 30 years i can tell you i've had more new cars fail on me than old cars.
It really does not make any difference at all with regard to reliability, it's an old wives tail.
If you choose your car wisely, service and maintain it correctly and diagnose potential problems early it makes absolutely no difference reliability wise if it's 1 day old or 10 years old.
I've delivered brand new cars with 2 digits in the mileometer and had them fail, cam belt jumped, coil packs, fuel pumps, immobiliser, had the seat switch on Lexus stick one time pushing me into the steering wheel
These where brand new cars driven extremely carefully.
As another point towards my case the Mrs's car was brand new.
It's used extremely lightly, serviced regularly and kept in a covered parking.
She's had new coils, fuel pump, steering rack, 2 x sets of shocks, new sunroof, 2 x drivers and 1 x passenger window mechs.
It's not just because it's a Renault either
Me mates Merc has spent 3 weeks of the 3 months he's owned it back at the main dealer, because of various problems.
My MX5 is a 94 with just under 200k miles on the clock.
It's done the Greece UK drive 3 times, toured around Europe, it's raced and tracked several times a year, is used as daily transport and is used for 90% of any trips we go on.
Off the top of me head it's let me down 3 times in 8 years.
All 3 times 100% human error
1 x flat battery
As the passenger didn't close the door properly
1 x blown motor,
Was faffing about tuning, knew the fuel pump was weak, ignored it and ran lean at full boost.
1 x Supercharger pulley bolts sheared
I'd used the wrong bolts).
What makes it even crazier though, is if you buy a older car you get a better car for your money, and if you pick wisely not only will it not depreciate there's a damn good chance that if you sell it after 5 years you'll sell it for more than you bought it for.
£20k will get you a pretty basic new Mondeo
OR
A last of the air cooled 993 Porsche 911, pick wisely and there is no way shape or form it'll depreciate any more.
Elise, S2000 even the new Mini holds it's value.
