2006 Lincoln Town Car to replace 2003 Cadillac Seville STS

I've been reading some Cadillac oil leak threads and someone mentioned a 2006 DHS that was leaking. Again, I could keep it and fix it , but what if it leaks again? I don't think the Lincoln will leak at all from what I've heard.

They both have their pros and cons. The Caddy is sportier and faster, and it has more thought out features. The Lincoln has a much bigger trunk and the keyless keypad on the outside of the drivers door. Here is a pic of the Town Car I'm considering.
