Well yes. And well no. My two- penneth here is thus (and please MO1, this is not directed at you, more at what some others have posted)
It is perfectly reasonable to express your opinion, provided you are respectful of other people's opinion.
I like my car and get on with it. So do many other people. This doesn't mean we are morons, or idiots, or talking sh1t, it just means, well, we bought a car and quite like it.
Someone else - like you for example - is having a bad experience. That doesn't mean that you are stupid or ignorant or jaded or whatever. It just means you have a car and for whatever reason you don't like it and have problems with it.
The general purpose of these forums is to share information to help each other out. This might be to share a problem or - or for those who are looking to buy - to share a general opinion on the vehicle.
Now compared to the VOC forum, I must admit I find this forum a bit more edgy and at times, borderline abusive, but there are more users over here than on the VOC one, so it is ultimately more useful.
Personally if we all just shared issues with the vehicles, shared positive experiences also and respected each others opinions then it would be a far better place here.
If you agree, please say. If you don't then please let me know and I will go back over to the VOC forum and sulk.
