Back in 1992, I drove my 91 Q45 from California (just short of AZ border) to Fort Stockton, TX in one go. Most of the trip was at a steady 145mph (for many hours). Average was 130-135mph, including gas stops.
(I eventually traded in that car in Aug 1998 with 102k miles on it - no transmission problems.)
Admittedly, that was in a car about 18 months old at the time. So, I do not know what stresses you might put now on the car going flat out for 70 miles. FWIW, I certainly would not do it on any tire that had any kind of flat and had a patch put in it - i.e., new tires only! With perfect alignment and freshly static and dynamically balanced!
