VL and RS

I just have a silly question about older Cavi's (up to '94). What's the difference between the VL and Rally Sport (what's the VL stand for?)

My Fiance claims the '91 coupe I bought from her is an RS and that her father took the emblems off the sides (Which ARE gone), but it's a 2.2L and I'd think something with the name "Rally Sport" would have a little more "Uuuuph!" in it.

PS: I know what the Z24 model is.

Everything else is pretty much dealer or factory rice. IE trim levels there is no difference in motors and performance except either a 2.2 or 24 (or what ever other option in that wide year range that was used for the Z24)

Thanks, anyone know what VL stands for?

VL=Value Leader. RS=Rally Sport
