In certain aspects preventative maintenance is a good thing, they are also things that no matter how on top you are that can still fail.
Take my RCZ. Low miles one owner. In the year or so I had it, along with x2 services I had to have done - chain, guides, tensioners and VVT sprockets, coil packs, coolant level sensor. After which I'd unfortunately lost interest in the car, which was a shame.
Compared to the Toyota GT86 I traded it in for, apart from routine stuff, that needed 1 headlight bulb in 3.5 years.
