Help with identifying LEGO sets
I believe that this covers everything:

Construction vehicles:


Diesel Dumper (6532)
Backhoe (6662)
Landscape Loader (6512)


Recycle Truck (6668)

Friends car (30103)

Fire vehicles:


Jetport-Fire-Squad (6440)
Launch Evac 1 (6614)
Rescue Runabout (6511)
Looks like just the car from Shell Convenience Store (1254)
