I just got my 2nd pursuit this year, it's a 2017, and I still have my 2012. Love em both.
Most of the advice listed so far is pretty good, some of it is maybe just a little bit anal but to each his own.
My advise for auction cars is this:
1) Don't expect the 'Carvanna' experience. The car you get is going to be dirty and filled with lots of little micro-damages. Dings, dents, scratches, etc. If you are the type of person who is going to be obsessive over these types of things then I'd recommend you go elsewhere. Seriously. If you can manage to love the car with some 'perp' marks on it you will be fine.
2) Make sure they sealed up the wiring holes. Particularly on the roof. Otherwise water leaks in and gets in-between the inner/outer body panels, then you are going to get rust in weird spots. Front of the rear wheel wells (inside the rear door area) is a popular spot.
3) Finding a rear door lock and inner handle kit can be challenging. My 2nd one came with the kit, found in the trunk under the spare tire. Had to hunt one down for the 2012. They get hard to find with each passing year. Another thing is the spare tires are usually full size and they do not fit in the sculpted out spot in the trunk, that is intended for a mini donut style spare tire. I personally prefer to have the full size tire and rim, which then has to sit on the top level of the trunk, leaving the spare tire well open. Get used to having one of the most awkward trunk spaces you can imagine.
4) Removing the glue form the old decals can also remove the paint. See how much this bothers you. In particular look at the plastic parts like the bumper covers. When they pull off the old stickers it will sometimes remove the paint right down to the black plastic. Removing the old glue residue can also be a challenge. Most commercially available adhesive removers (Goo-Gone) just end up just smearing it around. I have a pretty good process for this but it is going to be labor intensive. better get your 'Wax on Wax off' arms in shape.
5) Replacement spotlight bulbs are surprisingly expensive. (from what I was expecting) Most have a plastic front lens and they get funky after awhile. Yellowed and small cracks, dried out seal, etc. Water gets inside them and ruins em from the inside out. Look for bubbling and peeling of the chrome backing inside the bulb. You can sometimes find used ones at swap meets but still it's a gamble. Them newer LED ones are pretty bad ass but kinda pricy ($100+) I do like them but the LED bulbs are notably lighter so when you are pushing it getting on the freeway or racing for whatever reason, the light will randomly flip back from the air pressure. I've tightened up the bolt on the shaft by the the handle and now it only does it when I get up over 95. Doesn't happen nearly as often now but still causes a little minor distraction when you are ripping along. Actually may make you jump the first time it happens.
6) Center console and the related wiring are a pain but well worth it. My 2nd one was far easier than the first. When you purchase the console, make sure they include the air tub for the rear vents. Sometimes if you ask, they will also cut the wires to include both sides of the connectors. Those will really comes in handy when you try to put things together. Seems the civilian models will use the same plugs with completely different wiring pinouts so you can't just click mating connectors together. I got help here in the forums and it wasn't too horrible to deal with. Look for wiring diagrams in a book called the 'Upfitters Guide' they helped alot!
7) 100K+ mileage isn't anything to worry about. (I've got over 200K on the 2012 and it's rolling strong) Remember that you are buying a used car but to the prior owners it was a tool, you have to expect some use. If anything I would be extra suspicious of the lower mileage ones because it probably means that 'tool' wasn't used as much, probably because of accident damage or maybe the car had a weird problem and no body wanted to use it. Maybe someone puked in the back seat and the thing stinks. I can't say for your particular instance. Buying a car by looking at pictures you can only use one of your senses.
8) Resolve yourself to the fact that you are going to need some front end parts. It happens, especially in city driving. Ball joints and idler arms are pretty common.
Oh yeah, getting a trailer hitch installed will cost you extra on a pursuit model because they have to remove the exhaust system to install the hitch. It's not just a random up charge, this is an issue most experienced trailer places will know about but others find out the hard way.
I can probably give you lots more info but these were just off the top of my head. Sounds like you already know all the basic regular stuff to look for. Most auction places will disclose any known serious problems up front. Check engine light light is a pretty common one, and it's usually just the Evap code, reset it and your good for awhile.
