First let me say that I do not drive a SRT but I did recently buy my N/A car just late last summer. Prices can be all over the place and it is my guess that an average condition SRT would be in the $12-16K price range. Now, if car has very low miles like yours...that is a desirable car. Who wouldn't want a car with lower miles on it? So that's a plus in your favor. Time of year your selling can help get your price as well. Don't try to sell a convertible in the winter....you will get more money when the sun is warm and buyers can test drive it with the top down. How does the car run, function, body condition, any upgrades or all stock...etc. All this can play into it. I don't think your too far off on price. Honestly, I don't think you can get $19K but I don't know anything about your car. There are always people looking for nice well maintained cars and are willing to pay for them. You just have to find the right person.
