I haven't replaced an engine yet. There are a few that are ticky/knocky but far from their heart. These things don't have timing belts to change every 60,000miles. I've been waiting for something to blow up but these things are pretty bullet proof. The engine I was going to replace due to low compression magically came back to life(I think my compression tester was fubared or these things will run just fine with low compression). Inconclusive... Cvt's are for the most part pretty reliable. I've replaced a bunch of 2015 cvts but the only 2017 cvt I replaced wasn't a normal failure. I'm sure it was due to the driver doing an 80kph burnout on ice then hitting dry asphalt. But can't prove it.
These are easy low maintenance cars. I'd be curious to see the cost of ownership of a Mirage compared to something like Pryme's Corolla in the next 5 years?
