Most of the posts here are anecdotal in nature.
Here's another data set. It is a year old...
Here's a recent CR study...
As always, the devil is in the details. Bottom line numbers can mean whatever you want them to mean.
- If maintenance is expensive and owners can do their own, the cost of ownership numbers change. Is it fair to assume luxury car owners do less DIY work?
- Do costs tend to be more mechanical in nature vs maintenance?
- Do manufacturers offer better warranties to lower cost of ownership?
- Do dealers offer free services or good maintenance packages?
I had a '64 Bug back in the day; it was amazing; ran forever and asked for very little.
I had another Bug, fancy flares, wheels, body in much better condition. Never did run right. But it might be cool to have it now since I have the resources to fix it right!
Probably the cheapest car to operate (not to own) was our '18 Model 3 Mid Range. Replaced one of the Contis that picked up a nail; $400. Ouch. The 12v battery was going after 5 years; Tesla came out and replaced it for $120. Of course I only put 25k on the car for various reasons. Otherwise it was a jug of blue warsher fluid... Got $22K from Tesla on the trade-in last June, ouch! Ya win some and ya lose some.
