Let's see, they're both high maintenance, but you can always shut off the Ferrari - I choose the Ferrari. Ferrari wins the ear candy factor.
Eye candy-wise, tough choice - but I'm sure parts of her were fake.
Overall, Ferrari wins.
If I had the money to buy, own and maintain that Ferrari, I could buy all the eye candy I wanted.
Remember the 3-F rule. If it Flys, Floats or F*%ks - RENT IT!
That said, I've been married for 15 years (2nd time) and forgot the 3-F rule in a moment of weakness, which I haven't regretted.
