I had my SVX Westy up to 115 once, and it was still accelerating
fairly quickly.  It probably had another 15-20 mph left. I must be getting
on in years as I let off the gas - I am just not bulletproof and invisible
anymore.
     There were no other cars on the interstate in sight, and the van felt
rock solid (16 inch wheels and Hydroedge tires).
     I did cross a couple of states this summer at very high average
speeds.  I think I did Wyoming above 90 mph, against 10-15 knots of wind.
