Gilders – as well as cars looking very different in the flesh to the brochures or online, colours can look very different in a showroom (under artificial light, spot lights etc) than they do in daylight. Bright / sparkly colours in a showroom can look dull and flat outdoors. I’d check the blue one outside before committing. I’m sure it will still be nice, but better to be safe than sorry. I have fallen in love with colours in showrooms and then be underwhelmed when I’ve seen them outside.
