ANYBODY...PLEASE, TELL ME...(T.T)**.;*:.*',**;".*

I get most of my Sims 2 downloads from The Sims Resource and Mod The Sims. Here are some links to pages with cars and other vehicles on:

Mod The Sims:

There's quite a variety there, I'm sure you will find something you like!

P.S. You need to register for an account to download anything from The Sims Resource, and a few of the items require subscriptions (payment). There are plenty of free items on there though. Mod The Sims has no restrictions (all free, and you don't need an account).
