I have bought extended warranties on some vehicles, but not on others. I don't buy them on ATVs/UTVs or automobiles, because they tend to generally be pretty reliable. On an RV I definitely buy an extended warranty, because RVs as a whole are probably the least reliable thing you can buy. The manufacturer make a difference of course. You are wasting your time buying an extended warranty on a Yamaha or Honda. Polaris units earn an extended warranty. Can Am is somewhere in the middle. With RVs, I have never needed a repair on a Grand Design manufactured RV (Momentum Toy Haulers). But Forest River manufactured RVs will need repairs each and every time they are used. I owned a Forest River class C motorhome that needed to have the refrigerator replaced under an extended warranty. It cost $5000 to replace the refrigerator in that RV, because they have to remove the rear window to get the old fridge out or the new fridge in, because it is too big to fit through the door. That one repair more than paid for the extended warranty, and there were several other repairs that were covered as well.
I wouldn’t buy it. The two most expensive things are the engine and gearbox which are very reliable in can ams. The warranty is also only as good as the dealer. Most of the time when a warranty gets denied is bc the dealer/service dept doesn’t have a good reputation or it’s how the service dept wrote it up. Regardless I wouldn’t buy any extended warranty.
I think it depends. I bought a 2019 cab model. Took the 2 year warranty over the $500 rebate. The passenger door pwr window crapped out and was fixed under warranty so it was worth it. Plus, we use ours very little. Mostly hunting season and just before so we don't find issues for a while so it was worth it for us.
you can negotiate the price on the warranty, do it after you get the price you want on the quad. if you can get it for 500 to 700 for the extra 3 years i would. it could pay for it in one issue like the power steering needing replaced, that issue is not common but just an example.
