I can absolutely confirm that the manufacturers do reward loyalty to their network. My Merc S Class had a failed air con compressor outside warranty. Merc immediately coughed up 75%, which I am told was only because of my using a main agent. Was told, happens all the time where non franchised repairers find a fault just out of warranty and direct them to the main agent on the basis that Merc will cough up a contribution…..guess what…..they don’t, and where was the vehicle serviced is the first question Merc ask.
Specifically with Honda I have no idea why you would even consider Halfords for £100 saving, which in my opinion is not a great enough saving, to loose Honda goodwill.
When any new model is introduced, and this hybrid is completely new, there will be issues and faults that occur. These are often corrected by the main agent ,at service time, without your knowledge, and is one reason how the Japanese brands over the years, have gained such a fantastic reputation.
Honda, many years ago was the first vehicle manufacturer to employ IBM to install a software package to all of their agents. When a fault was found during routine servicing that fault was immediately relayed back to the factory in Japan, investigated, and a solution found to fix. This was then introduced to the production line for future production, in real time. This was so way ahead of everybody else at the time.
Of course the other consideration with Honda is the 5 year service package, which I got free, but in any event only costs around £500ish. An absolute no brainier and makes the service cost the same as Halfords.
These vehicles, whilst amazingly reliable, are at the same time amazingly complex. Would I let a Halfords grease monkey anywhere near mine…….not a chance……..but that is only my opinion.
