Make sure you have a car picked out before the new month begins, #1. There's a lot of guys trying to hit Unit bonuses right before the month ends, and it would be worth it to them to make $100 on a car if it means the salesmanager and salesperson are going to get a little extra in their check with a bonus.
The dealership I work at doesn't mark up prices on Autotrader, but I know of several that do. One thing it does usually do, depending on who maintains the inventory, is not stay up to date with the vehicle. A lot of dealers will ask way to much for a car when it first hits the lot, and the price will slowly drop until it's gone. Autotrader gets these vehicles in their database by sending out one of their employees to photograph and list the vehicle as a service to the dealer. From that point on, it is up to the dealer to list any updates (price changes) to the vehicle or remove it when it is sold. Well, when it is listed on Autotrader, It's listed at the initial price. The price of the vehicle it could have dropped in price from the time it was listed to the time you saw it. If you find a vehicle on Autotrader, drive to the dealership and act like you never saw it on Autotrader. If you contact the dealer through Autotrader, the Sales Associate will know that you are looking at a price that may be higher than what is on it now, and may go throw the higher price on the car before you come to look at it. I would Use it as a search tool and nothing else.
Here's a short list for SUV's w/ positives and negatives:
I would stay away from any Hyundai that's from 03-05; They're pieces of crap and don't hold value for anything. From what I've seen though; Hyundai has really started to change over the last two years and Hyundai is becoming a respectable car. An 07-08 would prob do just fine.
I don't know much about the Escape, but I do know that ford has a reputation of building one vehicle to run like a tank, and another made to fall apart within a year. Example: Ford Ranger, prob the best car they ever made; Ford Taurus, If it ran long enough for you to ever get in a wreck, you'd prob die. Sorry I don't know anything about the escape, It's been too long since I've had to sell cars and stay up to date with competitors.
Honda CRV: Great car, but if you find one for $13, it prob has a ton of miles on it.
Chevy Equinox/Pontiac Torrent/Saturn VUE: All the same car really, Saturn's V6 from 04-06 is actually a 3.5L Honda Engine with ass loads of Horse Power and will get you 25MPG on the Highway. The 4cyl that each of these vehicles use won't get you much better gas mileage than that. DO NOT BUY AN AUTOMATIC 4CYL SATURN VUE FROM 03-06. It has a Transmission (VTI) in it that WILL go out on you before 100,000 miles. The negatives of each of these cars are they're kind of rinky dink interiors. Not that anything will go wrong with them, but you'll probably have a lot of road noise, squeeks, rattles, and stuff from the interior of the vehicle that will be annoying. They're good cars and a great option. I love my Saturn VUE.
Toyota Rav4; It's a good car, comfortable; but it's going to look like crap in a year. Toyota uses the thinnest sheet metal possible on the car. You can dent it by pressing your thumb in the side of it. May not be important, but if you're planning on selling it in the future, this will effect the value. Also, like the CRV, if you find one for 13K, it also prob has a ton of miles on it.
