Comeback needed!

[stacy's stang]

Okay, it was Saturday night just getting back into Tallahassee with my 12 yr old daughter and 1 yr old puppy in tow. I'm a 38 yr old woman, trying to create an awesome ride that looks and sounds mean, but not really interested in going fast. It must be working because a car full of teenage guys pulls up beside me at the stop light and motion for me to roll down my window. So I did. They asked "Does that car really go fast?" I really didn't know what to say. Then they asked what is your top speed in it? Well truthfully it's been around 80 mph. Again, I'm at a loss for words and say something stupid. They light turns green and I floored it! Daughter starts freaking. lol. My husband had no advice for the correct comeback I should have given.
I was considering "Well the spedometer only registers up to 150 and my husband won't let me race anymore because we don't have room for anymore cars in the driveway." What do you think?
