I've ID'd the first two for sure but am having trouble with the last two.
All from Ep. 2.13
1994 Oldsmobile Aurora: 3 Star (used by villains a couple of times in this episode)
Pontiac Firebird: 4 Star (used several times in different episodes)
Some kind of Ford (the white car behind the Firebird): (2 Star, used by Capt. Bridger and lead detective for cover during the firefight)
Taxi, I believe a Cadillac? (2 Star)
