That tells me you live in Michigan. You sold it on 2010-08-17 (not 2011) to someone who registered the car in Florida.
Other parts of the document states the car was sold on 2017-3-4 at Warner Robbins, Georgia 31088 (had been advertised for $19,500) and apparently was registered to the new owner on 2017-3-14, in Florida. The report indicates the car is still registered in Florida.
The car is black and is an NA.
I recommend you hook up with Kappa owners in Florida and have them keep an eye out for a 2010 Black NA SKY with some 50K miles, (+ or -). Unless you winter in Florida, you will need to depend on what Kappa owners in Florida run across that fits that description and VIN. I assume you still live in Michigan. Good luck in your effort to reach out to Florida forum members and Kappa owners to find your car.
You might try to contact the County DOT office for the Georgia town of Warner Robbins and see if their records would reveal who the seller was there in their county of the March 2017 transaction. Not that long ago, they might just be of assistance.
Would be interesting if you cared to share with forum members here why you are pursuing finding the car. ?? if you so choose.
