The most expensive proposition was a new windshield, but your particular insurance could solve that. Spark plug replacement was a surprise as far as cost is concerned. I've routinely changed the oil and cvt fluid once. No other maintenance issues. I love the car. Incredible roominess in the cabin and very capable offroad when needed.

Pros: no other maintenance issues, capable offroad

Cons: expensive windshield, costly spark plug replacement

My 2015 outback has 140k miles. I just did spark plugs and belt, brakes. That's the only maintenance I've ever done other than tires and batteries.

I’ve had my cx5 since August of 23. Put 48k on it since owning it, bought used at 44k it’s been a dream come true. cx5 just takes regular maintenance like oil changes spark plugs and brakes..and another plus it’s a very sharp looking vehicle inside an out.

Pros: sharp looking vehicle

My RX8 also got pretty piss poor compression numbers. The only time it struggled with a start up was with literally the original 20 years old plugs it came with and I had to do multiple hot starts. It still started and carried on.

Pros: still started and carried

Cons: piss poor compression numbers

That price at 63.5k miles isn't bad imo. I spent roughly that same amount for my 2017 back in 2019 with around 40k miles (64k km). What's the service history look like? Have spark plugs been replaced, belts checked, engine oil changed at least 10-12 times by now? How are the pads and rotors?

I now dread doing spark plugs. Something that’s super easy to do on most 4 cyl cars is a PITA doing on my ej25.

Cons: spark plugs difficult to replace
