These are the Maxis World vehicles from the base game made available for Buy/Build.
Includes the cars, small planes, fishing boat, trolley and paddlewheel boat. I’m not including the train cars or the riverboat because they look a bit shitty on close-up.
These are regular deco objects (found in Deco > Clutter for 800§–65.000§), no cheats required; they also do not require you to download 10MB of stuff you already have (they are just catalog objects using the existing objects). All of them use the generic sculpture_noView tuning (i.e. they work like Maxis deco objects).
Note that the small boat has a boat footprint; you need moveobjects to place it on land.
