Well, that is wishful thinking on your part. From experience, being the owner of a 2014 Equinox with a 4 cylinder, I wished I would have chosen the V6. The 4 cylinder has the inherent problem of the exhaust manifold cracking and spewing CO2 in to the passenger compartment. GM is aware of the problem, but refuses to issue a recall. It will cost you well over $800 to get replaced. Secondly, the issue with the water pump. The most idiotic design GM engineers came up with. Replacing this item, due to it's design and placement, will run you well over $1000 maybe more. Some shops refuse to even attempt this fix, as it requires the purchase of a special tool. This is not a uncommon problem with the 4 cylinder, so the money you save with gas mileage, better put that in the bank and use it for the repairs that will happen. Kindly provide some evidence, other than gas mileage, that a 4 cylinder "by design" outlasts a V6! Opinions are just that, everybody has one, some are based on facts, others on fairy tales.My first Equinox is a 2018 Premier 2.0T so I cannot comment reliably on later models. What I can say is the benefit of the 4 cyl over the 6 cyl is obviously fuel economy and I4 engines will just by design outlast a v6 by many miles.
