There are guys paying anywhere from $25k-$100k over MSRP for the Z06's... Prices are starting to come down a bit, but there are still some insane ripoff deals going on now. Granted, its a legit supercar, but if I was spending $185k on a car, it would be on a McLaren, or an Aston Martin or something, not a Chevy...I'm sure they won't budge off that markup either. When I worked at Ford lots of guys thought they could negotiate a deal on a Cobra, Lightning,Roush car etc. but that doesn't happen. There was no discounting the specialty brand/cars.
Hell I still remember when the Dodge Stealth was new and everyone was floored by a rebadged Mitsubishi. I happened to be at Five Start Dodge on Riverside in Macon and saw two of them. At the time they were the only two in middle GA. I forgot what the MSRP was but that's when I learned what an addendum sticker was. They actually had a hand written Five Star sticker beside the Dodge sticker that read " $3500.00 Limited Availability Fee". If anyone actually paid that then they had some kinda head injury.
