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

Mileage: 77249 km

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

Vehicle: Mazda

Mileage: 30000 km

At around 120,000 KM plan for spark plugs. It's easy, especially if you get a 1/4" torque wrench and 14mm 1/4 deep well socket.

Pros: easy to replace

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?

A regional tire store / repair center "recommend" spark plugs on my Sienna at 92K for $850 (intake manifold has to come off to get at 3 of the plugs). I asked them what benefit would there be in replacing spark plugs at 92K considering Toyota sets the spark plug replacement at 120K.

Cons: unnecessary work

Vehicle: Toyota Sienna

Mileage: 92000 km
