GL to your Son in the chess tournament!
We do 2-3 road trips a year from NC to NJ, to see our adult Kidz every Summer, for the past ~20 years. Our ol' 2001 E53 does not miss a beat, in the ~700 mile each way drive...
That 1200 mile trip in one day is hauling azz...we can't do that kind of daily distance anymore, as we are boomer/geezers.
GL, mD
