Honda's reliability record means that residual values are generally high, so finding a bona fide bargain will require some patience.
Most Honda owners are fastidious and are unlikely to let service schedules pass by unnoticed. It'll be unusual if you find one without a decent history.
The diesels will be sought-after, so if you are on a tight budget the 1.4-litre petrol will be the one to go for if you are seeking a decent discount.
If you have a diesel model you'll be quids in and when it comes to negotiation. Your prospective buyer will have little room for manoeuvre, even if you do have a high-mileage example.
