Bringatrailer is a great site when low mileage.

Facebook on the Crossfire Groups would be another option. I find, oddly, within the community, sometimes people think prices are too steep, instead of appreciating an uptick in the value of the cars.

Also, as mentioned previously, I always make sure before selling a car that it is detailed from top to bottom (Wash/Claybar/Wax or Ceramic Coating), Interior wiped down with professional cleaner and Lexapro Leather Cleaner and Conditioner as well as floormats shampooed. I would even clean and condition/treat the top.
Then I would do an engine wash to make the underhood look nice and clean because you know a buyer will peak under there. After that, take lots of good quality pictures. This is all easy to do and VALUE added. When I see a car with a dusty engine bay, no records, dirty wheels, I take a step back becuase it tells me about the ownership and lack of pride therein.

Headlights should be conditioned. If you don't want to do it yourself, take them to Sam's Club or Costco or Walmart. I only am subscribed to Sam's but they will charge $40 for both headlights (wet-sand, polish and apply a UV Filter Clearcoat with a 3 year warranty). Can't beat that deal and they look like new.
Money well spent.

Re: Top not working. Get ready for someone to try and haggle you for it. Replacing ALL cylinders and pump isn't cheap. Maybe it would make sense to do a little diagnosing to see what the culprit is? Maybe something totally simple and cheap to fix like a sensor not connected or connected the wrong way? Have you ever messed with the hydraulics? Is there enough fluid in the reservoir or are any cylinders visibly leaking?

Then you can get the most out of this car. But trust me....even if it doesn't seem like it right now, you will miss this car. Sometimes we make these decisions because we had a couple of repairs or something else and we think it's time....then you regret it down the road. And lastly...maybe consider replacing the wife and buying an SRT-6 instead? LOL
