I don't think we have a downer on Caterhams or similar cars. I looked at Caterhams for a while and I think PaulJ still has his.
The thing is, as Beneviro wrote above, we know what our Morgans are like. We don't chose a Morgan because we don't realise how good other cars are in comparison. As a group we are often patronised about our choices, but these choices are not made in ignorance. Quite the opposite. Most on here could swop their Morgan for a modern which would be superior in every way.
But few do and thats what enthusiasts of other niche cars, and most journalists simply don't get.
