Whoa. It was a 90-120 run and he stuck right with me. He was alone and I had 4 people and a trunkful of stuff, but I didn't expect that. After cruising at 120 for a while, I let him go by because I don't like going that fast for long periods of time. He lost a little in the corners, but not much. Impressive. Couldn't tell if it was a Viggen or not.
