ehh.. try 221 (mwm) cars most of the cars here on vstanced work with it
for crashes...in the game folder there is a error-log, look there what causes the crash
most of the time it's a package conflict..for example rims or unnamed mods.
sometimes the game crashes without a reason..but hey, thats slrr al the way hehe
avoid dealership and buy cars from the catalog
tip: install mods one at a time!!!! so you know when you messed up with a wrong mod
last word: read the noob guide
