2001 Elantra GLS
Is it possible to add any of the trim features like Cruze Control, or anti lock breaks to a base gls? Has done/tried?
I’m pretty certain that my gls was the very base model, meaning that no extra trim features were added. It was my grandparents car so they probably got the least expensive version.Are you aware of the trim features of the car in the first place? If this is known, then you can know what can be added or not.
You can also get a monroney sticker that matches the trim for the particular car. The sticker will give you an idea of what can be added or not.
