lincoln towncar: which one? 85-89 or 2007+?

Hi guys,
I'm looking for advice on which to shop for.  I'm
looking at the Lincoln Towncars, but can't decide
which way to go.  

I can find old school low mile towncars for about as
much as I can find the last few years they made
them.  From what I can gather, I can't go wrong
either way.  

I want one for family road trips primarily and for me
to leisurely enjoy otherwise.  What would all y'all
recommend?

What pitfalls do either have?  

Thank you!
