I believe the cars used in the stunts were damaged beyond repair
I’ve seen car jumping scenes in which the chassis was clearly undrivably bent at landing. In fact they’d cut away fast from the landing because it was so obvious and the car had 2 more minutes of chase scene to run. (There has got to be a hell of a lot of crippled stunt drivers out there).

They had 10 or more of them. The jump/stunt cars were reinforced but only able to drive for the close-ups and then went straight to the shop.
Same for “Starsky & Hutch.”
Grave yard cars rebuilt one.
It can be done.
