Here in Lauderdale Corvette rentals run around $300+ per day with $2500 to 10K security deposit (depending on financial clout of renter).
This is for 100 miles. ($.75 each extra mile) Taxes and surcharges apply.
I'm in the (film and music) entertainment business. If we do any "advertainment" peices with Corvette (as we're being asked to), I'll make sure I get that sample run. Corvette and Cadlillac are promotion-happy right now, as they should be.
Right now we're working with Mercedes and they are generous with this type of thing, even to the general public.
I wouldn't be surprised if they don't already have a Z51 C6 Coupe sitting on there lot with a big "RENT ME" sign on the windsheld. There's a couple of places on Las Vegas Blvd. where you can rent them. But be prepaired to pay major big bucks.
