Given current used prices I wonder if you'd lose much
Not much on the car, but it's the 5 year warranty and service plan I paid extra for - the T&C's seem to say that they aren't refundable.
Yet, on other brands you get a refund for the unused portion of them. The warranty for years 4 and 5 hasn't even started yet so should be fully refundable if they were reasonable - yet doesn't seem to be.
However, you must be given the T&C's at the start so you can cancel within 14 days I believe... except Honda only posts out the documents once a quarter.
Huge legal mess, as you'd win with them failing to issue the T&C's immediately but it's the hassle.
Then it would likely kick off a class action lawsuit, as everyone who bought a Honda and wasn't given the extended warranty/service plan documents immediately also has a case.
