i believe the BMW 5-series in Ronin was an M5. In the chase through the city streets a Porsche 911 was used as the camera car.

the amusing thing about the Ronin movie is that after all those chases in the supercars, they end up in an econo-hatchback that doesn't crash at all.

in "The Firm", Tom Cruise drives a 124 coupe (or cabrio?)

in a movie featuring Navy Seals (Charlie Sheen, if i remember), they use an old benz that they drive down some stone steps.
