I think it depends on the colour actually.
I prefer a Ferrari but I wouldn't buy a red one (bar dark red), or a yellow for that matter. It's a car I'd buy in a neutral low key colour. But then I'm interested in the FF which is a front engined GT car with 4 seats and a V12. The 8 cylinder cars don't interest me (bar the new GTC4Lusso T).
I wouldn't even consider a Lambo, firstly there's the practicality and secondly and for absolutely no basis or reason whatsoever I assume the driver of a Lambo is either a footballer a wannabe footballer or a tw@t. But again it's colour dependent. Lime green and citrus fruit colours or shiny wraps fall into the more money than taste category. Grey or silver look like completely different cars. The thing with this kind of car is the engine and shape do all the shouting it needs, it doesn't need a dayglow paint job unless you're attention seeking.
Of course the Muira is excluded from all of this as it's a work of art, but it's a Million £ car and also reasonably likely to spontaneously combust.
It's a very personal thing.
