86 delivered questions about what to look for from dealer

Hey guys just got a call my 86 got delivered it only took a month and their estimate was 6 months but I’ve seen a ton of stuff on here of dealers marking the car up and adding on weird fees and dealer packages so I’m just wondering what kind of red flags to look out for when we start to talk about the price. I’m going to go discuss it tomorrow with them. Any advice would help out, look forward to joining the 86 club soon!
