Personally I think the ZL1 is better looking than the GT500....and it handles better as well according to track tests. Sure it's not as fast, but what do you expect when the ZL1 is only running 7 PSI and the GT500 is running 15 PSI stock. I've seen a few ZL1's in person and the interior is gorgeous with all the suede on the dash and seats. I prefer it over the GT500 as well. Theres always going to be people that like one or the other. Thats why both sell. Not all guys want a car that makes a ton of HP out of the box, but more of a "complete package" car. FYI I do like the GT500 as well, and wouldn't say no to either.
