@Robert: I guess you need a better commercial chief - I had no issues signing level 5 sponsors and my chief commercial "only" gets 150k/week - the bonus would be kind of expensive in case I win races or the championship, but with the money I generate from fans this expenses are covered.
I do not expect any progress on the car until I have a level 2 hq with extensions.
on the bright side, less staff is needed for research/development on every part in div 3
- the potential research level is not very high since there is just a handful of staff and I run a junior program - so only one designer work for my team. with 5 or more designers the potential is there to make progress but the expenses rise to "catastrophic"
so besides the potential level of research only the amount of spots prevents any progress - once you have done research on one part and switch to another part the "good" one gets worse very quickly- therefor it is kind of waste of resources.
however, more spots for research/development also would increase the expenses and will increase the speed to go bankrupt...
tricky situation there, the only reasonable outcome for me is to push income, keep my team on a low level until the circumstances turn to my favor (and I have at least a 9 digit number on my bank account, starting with a 5 or higher)
edit: Starting a team now is a complete different experience than starting a team in season 1 - it is much more challenging now, and potentially much more frustrating
