At about 7 minutes in, the car overturns and catches fire. This is the same footage as used in Cross-Up (1954). Note that the car that burns is not the Jaguar they were driving. The burning car doesn't have the sleek curves of a Jag and the windows are nothing like the ones on the car just seen. They obviously weren't going to set fire to a nice Jaguar.
In fact, the whole car chase sequence that leads up to the crash is the same in both films with police car FNB 578 chasing Jaguar LXP 202. Notice the buildings, particularly as they take corners.
