livin it up
has a lot of cars and trucks planes and many things to go with them like things to make a garage etc. Very good site
also trinkets and treasures
also a search at surfer sims and Ultimate Sims list will send back more links as well these as well as those a couple of those already listed are my favs but I really Love Killer sims of course you must subscribe to Sims Host to get into paid part of killer sims but hey you get access to So many sites for one low price so well worth it at least it has been for me.
and the livin it up
Hope these help
of course as always a google search is also a huge help in any search
