My wife has decided that she would like to get into a newer GX. We currently have an 04 GX470 with 277k miles and still drives and runs as it should. Overall has been an amazing vehicle. The GX pulls tow duty for our 4,500lb boat on occasion (usually 2-3 times per year) when we go camping AND take the boat. So, because the GX has been so good to us over the years, and she really likes the vehicle, we're looking at a 2014-2016 GX. Are there any obvious, or less obvious, things I should be looking for as problem areas or maintenance items I should be certain were completed?
