There are replacement cars you could use for vacation. I've seen a program at SimPrograms.com, www.simprograms.com that allows you to change the vehicle. Please be advise that there are no cars that you can drive.
I wouldnt recommend downloading stuff to substitute other stuff in the game... I think that theres a chance of ruining the game...besides...is the stuff in the original game that bad? I find those cars in the game rather reasonable...
I've substituted some NPC characters ok before, but I'm always cautious and back up everything first. I think the cars that came with the game are pretty cool, but I can see how it would be fun to customize them... it seems this game is ALL about customizing it!! Which is one of the best things about it actually!
I dont object to customizing...but I must warn peopl enot to substitute objects out of the game...seen to many cases with problems
