Mitsubishi Eclipse GSX vs BMW 740IL

OK, my dad seems to think that he 1998 automatic BMW 740il can take my eclipse from stop, and also on the freeway. I keep telling him that I'll eat him from a stop but on the freeway he'll kill me, but he doesn't believe me. And the worst part is he won't race me!!!!!!!!!!!!!!! Damn him. Anywayz what do you guys think will happen?

What engine do you have in the eclipse. For reference, I took down a turbocharged stock eclipse off the line, around corners and on the freeway in a 750il.
