Hi- second post here. I've been searching for a 2015 but now I see an interesting 2014 nearby. I've tried to read as much as I can on here but was wondering if there were significant improvements from a 14 to a 15? I know the owner and maintenance are the keys but wondered if there were really any other factors between the 2 years. Seemed like 14 had more complaints as it was the first year but would think they would have been addressed by owners by 2020. Thanks!
