Hey, So I was wondering where all the garage's are (the ones where you can change the look of your car) and if there is a mod that makes the Johnson house garage one of those kinds of garages.
There is a garage facing the johnson garage so why would you want that?
I think he is talking about the mod garages, like loco low riders and such. Check here for locations. GTA: San Andreas > Vehicle Modifying reference (by Kremit)
