You can compare similar vehicles and options and get manufacturer and invoice pricing online before you ever enter a showroom. But those clicks can be out the window when you hit the bricks of a dealer lot, due to vehicle availability. The dealer may have the model you’re looking for, but not in the configuration you want. So the dealer has your new ride in stock, but it is has different options. Floor mats — no, sorry, can’t sell it without the floor mats. Different paint, pearlescent, costs a bit. Turbo engine — you’re definitely going to want. Plus the inch alloy wheels instead of the standard inch steel ones. There are also heated seats and mirrors, and a navigation system — it’s all part of a package, can’t order that stuff a la carte. This is a high-demand car, the dealer says.
