My first car was a E46 316i, under 100tkm on odo, had it for 3 years, literally gave no problems.
Sold the E46 and got a E39 530D because I love them. Has been reliable so far, I've had it as daily for almost a year now and the only critical problems it has had are that the alternator gave out after a couple of weeks owning and EGR thermostat was bad.
Pros: reliable, no critical problems
Cons: alternator gave out, EGR thermostat bad
Vehicle:
BMW
Mileage: 100000 km

Mazda's DO NOT like aftermarket alternator. Most don't work out of the box. You need to get a genuine Mazda alternator.
Pros: genuine Mazda alternator needed

My 2017 Mazda 3 touring felt like it was cursed. I had the direct high pressure fuel pump injector go out like 1.5 years after purchase. About 2k for just that repair. Thought that was the end of it until the following year where there was a persistent evap problem that nobody could find, despite clearing the code it wouldn’t pass smog. One smoke test and several hundred dollars in appointments later they found the smallest leak from one of the hoses, replaced it and passed smog. Then the check engine light saga started, at first we thought it was the battery/alrernator until after replacing both it kept happening. Turns out that was the start of my catalytic going out(76k miles exactly). Idk if it’s Stockholm syndrome but i did trade it in for a new Mazda. Hoping the curse has been lifted.
Pros: passed smog after repair
Cons: fuel pump injector failure, evap problem, check engine light, catalytic converter failure
Vehicle:
Mazda
Mileage: 76000 km
