First (2 pics) Double decker bus. 3 stars. is a AEC Routemaster.
Next 2 London cab. 3 stars. looks a 1993 LTI Fairway Driver with rear-view mirror over front wings.
Police Cars (2 pics 3 ***) with front and rear views (15&16 pics) are 1992 Vauxhall Astra MkIII.
Police car (pic 20 2**) looks a before 1992 Ford Sierra Hatchback.
London cab (pic 33 2**)another LTI Fairway but before 1993.
Police car (pic 35 2**) probably Vauxhall Vectra (model A) before 1995
The next one (pic 36 red car 2**) is a Vauxhall Corsa (1983/93)A or MkI 5-door hatchback
"Greyish car in the center. 1 star." (pic 40) is a Fiat Uno (Hatchback) problably Series I.
"Another police car, appears to be a different model. 1 star." (pic 42) is a Rover 800 (Hatchback) before 1992
Finally to say that pic 19 (Limo. 3 stars.) also looks a Vauxhall but with that body I can't add nothing

I suggest that with 10 or more pics, maybe would be better list pics by numbers
