Well the zl1 is going to be faster in a strait line for sure and have a back seat.

the grand sport is a better looking car IMO but not as functional.

IMO if you can live with a GS get the GS though.

there are elements of the new zl1 the font grill and rear spoiler that just don't look good at all. I can't find one angle on the GS I don't like if I did not have young children I would be buying one.

performance wise they both will suit most people well.
