Well despite the concerns on the 1.5 turbo, I've ID'd a pretty good deal on a '23 Integra. Should I pay $2,500 to have it "Acura Certified CPO"? Seems like essentially I'd be just paying to extend the warranty from 60k to 100k?
I wouldn't, I'm Not a big fan of extended warranties. If you avoid all extended warranties you will save enough to deal with the few problems that do arrise. If the engine is an issue, then it will likelt become apparent before the end of the std. powertrain warranty, or there will be a recall or extension of some sort.
