Okay, seriously, I just am not one for getting up-sold at time of purchase. When the 3 yr warranty is up you will be deluged (including by legit Honda) with warranty renewals. I have never seen a price hike that says 'you should have gotten it when you bought it.
I purchased an extra's package on my 2016 HRV which included an extended warranty to 5 years. I'm glad I did as the car has developed a transmission issue which is still covered and which wouldn't have been the case under the original 3 year warranty.
Hindsight being what it is, I say it's not worth it. I would not buy the HondaCare warranty again. The list of what they won't cover is substantial...the fine print in the contract. So it's not truly a "bumper to bumper" warranty like the sales people pitch it as.
