Hi everyone, new member here looking at buying a 2015 Cruze 1LT. It's Siren Red Tintcoat and loaded with about every option: Technology Package, 1LT Driver Convenience Package, Sun/Sound Package, and the RS Package. List price is $20,600 after the 15% off MSRP sale Chevy has going on. How much do you guys think I should offer the dealer for it, 18k? I'm looking for a new daily, this would be the first brand new car I've bought. I also have a 2010 Cobalt SS Turbo.
