Well I have an Azure (blue) Roadster, my girlfriend drives it occasionally and loves it each time. In fact she gets quite a bit of attention when she does.... maybe thats why she likes driving it
As far as waiting until summer is here to drop the roof... I did last night, as long as it's above 6c and not torrential rain its good.
I say go test drive a Roadster (any colour) to see if it's for you then start the search.... I waited about a year to find mine.
