(naming credits go to @Duster02). Here's a cheap 2000s sedan. Mostly inspired by the Mk1 Dacia Logan, but with some genericization and Mk2 Renault Clio inspiration. Pretty much base spec, which means a 1.2 engine and sparse equipment, without even hubcaps or a radio. https://www.beamng.com/resources/2003-carpath-ch2.6446/
