I commute from Windsor, On. Canada to Detroit 5 days a week. I generally do most of my racing/challenging on the Canadian side because the cops never seem to be on the road (they're probably busy helping people instead of writing tickets - but that's another discussion). I have a 96 STS with exhaust upgrades and a K&N (+-320hp I figure). I pull onto the freeway and I notice this silver beemer making tracks in the fast lane. He looks like a player, so I start closing in on him :coolgleam . I thought it was just a 540 until I got close enough to see the "M" cladding. OK, now I'm behind him and he's behind a tractor trailer. He swerves into the right lane to try to get around the truck, but that lane is also blocked a few cars up ahead by another smaller truck. By this time, I had a good idea he knew I wanted to test his skill (the way he swerved into the right lane said it all). My lane starts to move ahead of his and ultimately the truck ahead of me changes lanes. I don't just want to leave this guy behind, so I pull in front of the truck. Ok, so we're both in the right lane separated by two trucks and a car. I check my side view and see him swerve to the left lane and start to punch it past the trucks. I think he's just gonna roll right past me (I planned on chasing him down ), but he pulls up next to me, slows to match my speed (+-70mph), downshifts and immediately starts to pull on me . I put the pedal to the floor and followed him to about 110, but the faster I got, the more car lengths he put on me. He nearly effortlessly walked away from me. I'm a good sport, so I gave him a friendly wave when he exited off the freeway, but that's the first time I ever felt decidedly whooped in my STS. It didn't feel as bad when I found out the newer M5's have just under 400hp stock, but dammit WE NEED SUPERCHARGERS!!!
