Hi Everyone, My name is George and and I have lurking around here for a couple of weeks. I am thinking upgrading to a newer SUV. I have a 2007 Chevy Trailblazer LT 4x4 that I have just paid off. My fiancée bought a 2015 Acadia and I have to say I have fallen in love with the idea of a newer vehicle. I have always loved the look of the full size GM. SUV and am looking into that idea now. I was hoping to get some ideas and opinions. I know this is a very subjective question but what is the most preferred year? Is there much more of a difference other than appearance between the Tahoe, Yukon, and Escalades? Which vehicles have the best headlights? Which are the best candidates for HID retrofits? What are some of the most popular, must have mods? Thank you all for the time. I look forward to hearing your thoughts, ideas, suggestions, and opinions. Have a great weekend! George D.
