Ok I raced and lost.
Well kind of, off the line the Honda took me and from a rolling start, at 40mph. But on the highway I pulled on him above 90. It was fun and my friend was impressed by the MB it has 200k more miles on it than the Accord and I out braked and out handled him, thanks to my sticky Yoko's.
All good fun, future races: 300SDL vs. 1999 E300D; 1995 S600 vs. any Caddy or Vett, that wants to go.
