Chevrolet Task-Force (1955-59), here with the 1955-57 front fender. The small bed indicates a ½-ton 3100.


On the right: a 1980+ C-Series, due to the external mirror. I'd say a 1980 model only, as it seems to have the 1973-80 flat hood.
On the left: a 2000-06 Tahoe.


2WD model (it doesn't seem to have a front differential) with a 1985-87 grille, so either a 1985-86 C-Series or a 1987 R-Series.


As already said by Baube, a Lotus Esprit. If I'm not mistaken, a 1981+ S3/Turbo which seems to have Turbo written between the door and the rear wheel arch (like this one).


1997–2002 LTI TX1, or more likely a 2002-06 TX2, as 250 LHD models were imported in USA in 2003 and 2004 (see also here).
From what I understood, TX2s look almost the same as TX1s (some small details, like the rear door windows are different) but have a more modern engine.
