The wife and I are contemplating downsizing her Expedition to either a Buick Enclave or GMC Acadia. Curious to see if you guys have any "go to" tactics for haggling on a used vehicle at a dealership. How do you land on a number you're happy with before you go in? I'd rather burn my eyebrows off with a lighter than deal with a car salesman, so I'm not exactly looking forward to the process
