Visit Car Dealership Early
So, you already know that weekends are too busy to count for cutting the best car deal for you. Being extremely busy with their advertising campaign run to draw in as many potential customers as possible, salesmen will be reluctant to bother around with you (in fact, the one of the crowd) if you do not look quite ''reliable'' to cut the deal. What they can actually do is just ''broom'' you out and switch their attention to another customer.
You also know that going to a dealership either early or in the middle of the week can turn out to be more beneficial. This can be applied to the times of the day too. Your chances to get the best deal are greater in the morning because this is naturally the slowest part of the day.
If you go for a car early, you'll get full attention of a salesman: no distractions, no spot delivery scam, just you and the dealer. In fact, we - car dealers - just love making car deals early in the day; most often it is the best way to get started which ensures pretty good mood for the rest of the day provided nothing disastrously wrong can happen. However, be sure not to relax much because you are here to cut YOUR deal and not theirs.
Go for your car early on Tuesday or Wednesday morning if you are quite serious about all the stuff. These business days are the slowest ones and you are more likely to get a car at a pretty low price if your negotiations are a success. However, remember to do preliminary research to have more arguments than the dealer you may be going to talk to.
