115 in my '03 Ram 3500
105 in my Saturn SL2
75 in my '72 CJ5 (It could go faster but not sure I could keep it on the road.)
I think the best was 95 MPH in the Ram for 2 hours in an emergency run from Clayton, OK to McKinney, TX. I was pulling 7K lbs. of Jeep and trailer behind me. I was trying to get a friend to DFW to catch the last flight out to California. His dad had a massive stroke in Sacramento and he was trying to get there before he passed. The interesting part is it could have gone faster.
