Last time the F1 team went bankrupt was Fitzpatrick-owned Manor Racing ahead of 2017 season due to financial problems and struggle to find new buyer. Hispania HRT, Caterham, Super Aguri, Arrows, Lotus 1958-1994, Pacific, Simtek, Forti and others were the victims of bankruptcy that time. I believe if budget cap enforcement in place, F1 can attract new teams from F2 and others like in MotoGP did during Claiming Rule Teams (CRT) days in 2012-2013 and Open Class days in 2014-2015 for the new independent privateer teams. New teams can save money by partnering with popular chassis manufacturer brands like Dallara, Oreca, Swift and others. The idea of independent privateer teams like CRT MotoGP in the past is the good idea for saving the sport. If new teams build the in-house chassis it could waste of money.
