In Need of Advice

Hi there

I recently lost my precious 1996 BMW 850CSi due to transmission problems. So now I'm searching for a replacement. These are the cars i'm looking into:

2004 Jaguar XJR (My favorite)
2004 Mercedes-Benz S55 AMG
2003 BMW M5

As you can see, I'm a girl that loves big engines!
What do you think?
