I was leaving work on my way to lunch. This e36 M3 was in front of me. Looked like he might have had an exhaust. Anyway, he just took off down the road going pretty fast. We ended up next to each other at the light. I wasn't going to race, I just wanted to get something to eat. So we both take off calmly from the light. I get up to 2nd gear, doing about 20-30 mph, and I hear the guy's engine screaming but he's hanging right at my rear passenger door. At this point I figure he wants to race so I floor it, and he does the same. He immediately pulled ahead by a nose. I kept even until I hit 3rd, then starting pulling on him slightly. We shut down at 80 at a red light. Guy gave me a wave and I waved back. Wish I had my turboback back on so I could have given him a nice thrashing, but it was a fun little run.
