Should I let myself down???

Hello dear community! So, I’m currently in a small town.A colleague of mine drives a sow old Alpina B6 E-21, faith bj 80. He said when I would finally buy a real car and so on… I did!He said that I should show it to him.He wants to race with me, but I don’t think so much about this kind of child-riding.On the other hand, I would like to teach him a lesson if I can!!!That’s also s o one question, the thing has 200hp and 248Nm and certainly weighs only 1080Kg or something plus the 100 of him I already drove with, is net so the rattle, till 4000 goes at all nothing at all, but then he runs already neatly, and laaange gegen hat der, bis 100 einmal schalten!!!! He wants to get out of the stand up to 100 and on the AB from 100 to 200!So what do you think? Should I get involved, or rather remain faithful to my Lienie?
