Ultimately that is the thing isn't it, 30, 50, 70 or 150million is still a LOT of money. Either they can spend more, or simply make more profit, I fail to think of a single situation in which you'd refuse to take money ...
Yep. Exactly.
If you get £70M. Take it. If more, then take that instead.
Basically, F1 cars are billboards - they are their to earn paid advertising.
Also, McLaren operate like a corporate business. When racing, us fans mostly hate the grey suit, decision by committee style of decision making. But when it comes to getting sponsors, this is the best way of attaining them. The grey way works a treat.
Back in the early 90s when Williams were going head to head with McLaren, both companies were run and financed (similar budgets) in a similar way. But as times progressed McLaren spent more time/effort furthering their business. They started making road cars and got into bed with Mercedes. I believe they have doubled the size of their factory in order to accommodate the road car manufacture. Williams on the other hand focussed purely on F1 racing and as a result, financially got left behind.
When it comes to making money, getting sponsors and marketing, to my mind, McLaren are by far the best in the F1 business. And this is what strikes me as odd - that McLaren cant get a title sponsor.
In any case, for me, I care little about their sponsors or livery. I want to see them make a fast car so Alonso can battle Hamilton (Merc), Vettel (Ferrari) and Ricciardo (RBR). It would be fantastic if all 4 teams could produce a competitive car, for 4 great drivers.
