I stopped by the dealer to look at this one. Since this ad doesn't belong to a member, I'll give my impression.
The car isn't particularly clean inside or out. The interior carpets look like they may have been given a half-hearted shampoo, but there is fair amount of soil and stuff in crevices. The creases in the seats could use some work as well. Overall the condition of the interior is good with just some minor scuffs, wear typical of age/use and some missing bits as noted above. It's by no means filthy and there were no funky smells (smoke, pets, kids). The exterior looks like it has been siting outside for 6 months; the paint is dull. The nooks and chrome pieces on the body look a little weathered and scaled. A thorough, professional detail would probably remedy most of this.
The undercarriage wasn't as bad as I expected given its life in New England and Park City, but there is definitely a fair amount of corrosion. The troughs in the wheel well areas were filled with gravel and debris (you can actually see this in the dealer photos). Under the hood there were no visible signs of leaks from the water pump or valve cover gaskets and the level of corrosion was minimal.
Contrary to the photos, the wheels and tires from this 200 have been cannibalized and replaced with a set of gaudy aftermarket 20"+ chrome gangsta wheels and low pro tires. I pointed this out to the array of sales staff I encountered during my visit and each time I had to pull out my phone and show them the pics from the link above to get them to believe me that the wheels had been swapped out.
For me, the wheel/tire issue is a ~$3k problem right off the bat notwithstanding the mediocre condition of the rig. I was content to be on my way after about 10 min of observing the above issues, but the sales manager and dealership manager encouraged me to take a test drive on the premise that they could easily swap some satisfactory wheels/tires if I liked the car. I agreed. As we were pulling through a series of wide 90* turns to make it out of the lot I could hear a loud grinding noise from the front right tire. I got out and sure enough the trashy aftermarket wheels were rubbing against the wheel well/inner fender apron--and had torn the bottom portion of the wheel well away from the fender (probably when turning in reverse). The car isn't remotely roadworthy with those wheels. I nursed it back to its original spot with the entirety of the test drive being about 300 yards round trip.
For some reason the salesman (who was a very cool guy) wanted me to go back in to meet with the manager. Maybe just as a follow up to our earlier conversation about swapping wheels. I began to describe the issue with the wheels and he just shrugged his shoulders with a blank look and picked up a phone that was ringing at his desk. That was that.
This 200 is by no means a turd, but even at the reputed trade in price of $34.5k and with the wheels as represented in the ad, it wouldn't be a great deal IMO. As it sits with the aftermarket wheels, slightly damaged, dingy and multiple owners--not a nickle more than $30k. The staff at the dealer may need to reevaluate their approach with this rig, but I grant them a little slack as this is a very large dealership and not everyone is an enthusiast.
