Which Toyota would you trade in and which would you keep?

2016 Rav 4 xle (13.5k)
Miles: 110k
Issues: 1 second cold start rattle, moderate rust on undercarriage

Or

2008 Highlander limited (6.5k)
Miles: 155k
Issues: paint fading bad on roof and hood with severe rock chips, mild click when turning (cv axle/boots probably will need fixing)

Planning to buy a Sienna and I will have to choose which one to keep. The legendary 2gr-fe v6 or the beastly 2ar-fe
