Saab actually produced a great supply of spare parts through its life is the thing. And I imagine they used a lot of standard GM parts during the time they were owned by them. 
  
 Tesla isn't exactly doing well in the spares department, which is why you see stories of simple repairs taking weeks/months

Tesla can't even source their own OEM components adequately.  An approved, post-bankruptcy servicer/manufacturer would be shit out of luck. It'd take 2 months to get a new steering wheel.
