Not in my experience. You either pay in depreciation or in maintenance, there is no escaping car expenses.
A 10 year depreciated car may need a timing belt/water pump, possible head gasket issues, possible transmission issues, etc.
And, in snow belt areas, you start to run into rust issues 15 or so years on.
A nice new BMW SUV is likely to depreciate 30k in 5 years, but that same car is extremely unlikely to need 30k of repairs if bought after 10 years and kept for another 5.
More critically you’re also paying dramatically more in sales and property taxes.
The electric water water pump alone was $2,000.00. $1,200.00 in parts and $800.00 in labor. This is basically a “maintenance” item. The car has less than 100k miles and is on the third pump.
The electric pump is great from a performance/efficiency perspective because the car can make choices about coolant temp irrespective of engine speed. It's a horrible device from a reliability perspective though. I have already been stranded by it once.
My turbos are "fine". But I know they will fail in the next 30k miles. In talking to my mechanic the prices fluctuate quite a bit, so I am going to start keeping an eye out and just buy a pair to have on hand when mine finally let go.
The reality is BMWs just have a lot of stuff on them and so it is a numbers game. Things are going to break. Cars are a hostile environment. This is compounded by the fact that it is a BMW. I expect everything to work. If it was a used Corolla I may not complain as much about the seat mechanism not working perfectly every time.
Additionally BMW also expects the car to work perfectly and the car is eager to tell you any time something is abnormal. This creates something of an illusion of unreliability. An old Toyota also has a lot of problems, you just don't notice until you go looking.
And finally, dealers are predatory. They take advantage of the reputation of BMWs as expensive unreliable cars and sell unnecessary services, which perpetuates the expensive/unreliable reputation.
I'm also lucky enough to be trained in vehicle maintenance; The only service I've had done by professionally were recalls and when I didn't have garage available to do the expansion tank (and Pep Boys didn't have a supply chain, so I got my choice in parts)
Head gasket shouldn't be a problem if the pump and coolant are changed before they go bad.
Anecdotal source; bought a 7 year old bmw at 123k miles (timing chain is still good at 185k), clutch is still good, brake parts cost $250, shocks less than $500, a valve cover gasket and oil filter housing gasket. Coolant expansion tank has to be replaced every 5 years ($150). My 10 years, 180k miles has been a better experience than many friend's first 5 years.
