I've managed to trash the plastic pan that lies beneath and across the engine compartment at the front of my '93 850 SE Saloon / Sedan. (Drove up over a high kerb.)
Its function appears to be to protect the radiator and whatever else from road debris and/or to improve the aerodynamics underneath the car.
I'm loath to replace it on the basis that a) it's likely to be expensive to do so and b) it's probable that I'll trash it again soon (!).
On the other hand, if it's an essential item, then I obviously need to get it sorted.
Comments on this pan's importance would be appreciated.
TIA,
Stuart C
