Hi, 
GTA SA is the only computer or console game I play.  I am always thinking about ways to change it to better suit what I like.  One thing that has been bothering me for a long time, is the fact that the Hermes vehicle lacks any fun mods in the Trans Fender shop.  I think the Hermes and the Hustler should be modded in the lowrider garage.  They are both asking for flame paint jobs like the Broadway, Blade, etc. 
So, 
Is there a way to mod the Hermes and Hustler in the lowrider garage instead of the regular TF garage? 
If not, is there a way to change the modification options for these cars in the regular TF garage? 
What I really want is the ability to add a flame paint job to either car where I can change the colors of the base coat and the flames. 
I already tried changing the "carmods.dat" file.  The cars that can be modified are listed in the file, grouped according to the garage in which they can be modified.  I added the Hermes (with the Broadway's list of mods, into the lowrider group.  Nothing happened. 
Also, one more similar question.  In the import garage, there is a wheel called "Shadow," which looks like the vintage 5 spoke wheels on muscle cars.  How can I add that wheel to the other garages? 
Thanks for any help. 
Justin
