A Ruby Red Limited Ed should be pretty well loaded. Plus, this is a 5 yr old vehicle w/13K miles. You may be able to talk it down a few K. Finding another with comparable milage would be tough. About the only thing you have in your favor, is that its now not the latest generation.
Any cosmetic issues are a obvious place to start. Make sure the sunroof and rear window functions, same with the front and rear cameras. Anything inoperable would be a deduction. 1st gen's had a recall for a transmission software update and were known to sometimes melt the # 27 fuel pump fuse, which there was a up grade kit that relocated it to the #70 slot and increased the AMP size of the fuse.
