At first I didn't like the livery but it has grown on me. It's unmistakably McLaren. Will look great on track. A lot of other teams have tried to copy McLaren colours through the years.
Ron does really like silver/grey, good on him for not giving it up. It's a colour that is associated with Mcalren, not just because of Merc. I thought Honda might have wanted something different and more Honda oriented (white), maybe Ron stuck to his guns again.
Lack of sponsors don't bother me as it looks cleaner. Team don't seem to be worried about it so we shouldn't either.
