Actually, I just took screenshots of all my cars (106) and all series progress prior to 6.0.5 (but more anticipating the 6.1 series restructuring) which took me maybe 20 minutes. Did not dive into each car's individual upgrades, but at least the car screenshot shows X of Y upgrades completed which gives some proof if an upgrade screws up.
