2013 Platinum, or 2019 Pro. Which one would you take?
97000 km on the pro, 180000 km on the platinum. Both are in 9/10 condition and are always maintained over and above what Toyota recommends.Depends on price and needs, also miles, condition underneath etc.
You assume correctly.Is one paid for?
Do you have kids?
As you mention getting something more economical on fuel you may also want to consider keeping the truck you owe the least amount of money on.
I would assume the Platnum may be paid for and has more space for kids. If that is the case sell the PRO and get rid of that payment. You can buy a lot of fuel for the cost of a monthly payment. Buy a Toyota Carolla that gets 30-40 MPG. It will also be less expensive to insure. Instantly your finances are better.
