Get the 2018? Sell my beloved 2006? What would you do?

No way! Not on a salvage vehicle! There's a reason is totaled,,, it's repairs cost more than it's worth. I'm sure you can cobble it back together, but it'll never be like your unmolested 2gen.

 

I was in a similar position as the OP; cruising towards retirement and wanting a truck! I have a 2007 FJ Cruiser with about 160K on it and absolutely love that vehicle. Since the FJ is long paid for and does not cost that much to insure, I decided to hang on to it. Unless you retirement budget is so tight that you cannot afford to insure and maintain both trucks, I would keep them both like I did!

 

If you live where rust isn't a problem you can keep a vehicle for a long time with good care.
Step up the maintenance and preservation of your 2006 and start making monthly payments into decent investments.

 

Insuring a salvaged vehicle is a good point to bring up. Also theres got to be some decent damage to it that most likely is more than just cosmetic.
