heres my 2cents,
Honda servicing your car is not neccesarily a bad thing, because it does add (as som1 said) peice of mind when selling your car. Also , they do specialise on honda, so theoretically you are paying for expertise.
However, I wouldnt take my car to a honda workshop. Reason being, If i have a problem (which i can't fix) , I take it to a SPECIALISED honda mechanic who is very well known as 1 of the best mechanics for Honda's in Syd. Im sure at least half the ppl in syd who are on this forum at least know of Rob at Hannys, and I have seen about 30posts where ppl are complimenting hannys and reccomending them.

I am not saying hannys is the ONLY decent mechanic i am saying he is a trusted mechanic by alot of people on ozhonda, and therefore its a pretty safe bet they will do a good job.

Now, I will never take my car to ultratune, kmart tyre and auto, and big commercial mechanic, or any pitstop mechanic who thinks they can work around a honda. Reason being, if there is a specialised honda mechanic who only works on hondas, compared to your friends cousins mechanic who works on kia's and fords I would choose the honda mechanic.
Also, places like Hannys are not expensive. They are actually cheaper. They use only honda fluids (or honda equivelent) and are generally pretty cheap.

So if your asking for a mechanic ,LISTEN to the people off this forum, obviously they drive hondas and have trusted mechanics, and if they all reccomend a certain place then go there.

and for a post earlier on, YES most ppl have no idea how a car works. Im still at school, and ppl who get their P's and ring me up and say, oh my interior lights arnt working or, oh this and that dont work, they don't even know how to change a bloudly blade fuse on their amplifiers or in their fuse box.
There are alot of stupid people when it comes to cars, simple as that. Alot of people say they have a problem, and don't research the problem or figure out what it is.
I am a person who always has to know why something doesn't work . A simple "oh the ..... doesnt work" isn't good enough unless I know why. thats just me, im sure alot of car enthusiest are the same.
anyhow, just thought i'd give input.
