there is just no evidence to support the claim that the car is ****. it is all subjective.. What is a **** car for some may not be a **** car for others.. A 3/4 best car on the grid is not a **** car in my book.
It depends on a lot of things. Examples:
If you´re in a team expecting to win the title, it IS a **** car.
If you´re in a team expecting to score a point here or there it´s not.
If the third/fourth car is from a team expecting to win titles, and it´s close to the first two ones (2003 McLaren, 2010 McLaren, 2012 Ferrari) and still allows you to challenge for races or titles, it´s no **** car.
If the third/fourth car is nowhere near the best ones (2006 McLaren, 2008 Renault, 2009 McLaren) and doesn´t allow any of that to happen, it´s a **** car.
