I think exclusive series is only a catchy name.

Everyone has his strategy. Mine is to upgrade cars in WTTT and get 100GC every week. With exceptions of course, I didn't upgrade bathrust cars, so it has been tricky to keep up in group B, but it has been quite profitable to me. I haven't upgrade any car in 3 weeks and I'm still in group B, but next week could be different.

Also few weeks ago we had the chance to upgrade Ariel atom which was very cheap.
