I took my dad's C230 to prom when I was in HS. We didn't have the 240D yet, I might of taken that then. Naw, the 230 has a nicer interior. As for the tails, I think that it goes better with the old car. The 230 being newer, I went tailless and it worked better. :p Are you going the vest or cumberbun route? I went with the vest and then the little tie thing instead of a bowtie. I kinda wish I had gone with the bowtie, my girlfriend at the time was upset, she wanted the bowtie, not the 'little tie.' Oh well, have fun and drive safe.
