Wow - lovely thanks for sharing
Before anyone buys check out the thumbnails -they are very nice, but there are only 10 vehicles with multiple colours to make up the numbers, from what I can see.
In fact here is the detail:
The 60 TRAFFIC models are divided into four categories. The category and number included in each are:
· 6 Sedans
· 2 Suburban Utility Vehicles (SUVs)
· 1 Pickup Truck
· 1 Station Wagon
Each TRAFFIC category is presented in six body colors, differentiated by detailed, high-resolution texture maps. Each model contains between 2,000 to 2,500 polygons and can be divided into the following hierarchical levels:
· Vehicle Body
· Vehicle Interior
· Individual Wheels with Tires
· Vehicle Glass
· Pickup Bed (Pickup only)
The TRAFFIC models are presented both individually and in groups. The individual models are presented in separate subfolders within the “3D Models” folder, according to vehicle type (Sedan, SUV, Pickup, Station Wagon). The grouped models are located in the “Parking” folder and are arranged in standard parking patterns that can be quickly used to fill parking lot areas.
NOTE:
For Max users the free model loads into Max 5.1 and Max complains that it uses an obsolete or older format - so I guess that Max 4 is this models base.
Here is a picture of it rendered in my Max:

Looking nice indeed - thanks for sharing -
In terms of B3d output the textures are NOT powers of 2 so there are some gumblings from Pipeline.
