Certified Used or new

[mattnxtc]

Ok so I am lookin to probably make my first real car purchase now that I have a full time job and what not. I am lookin to get something like a 4 door accord/altima/camry.

My 2 real options are:

Certified usedv (02-03 models):
Pros: cheaper, warranty, can probably get a better model
Cons: going to have around 40-50k miles on it

New (07 models):
Pros: its new, warranty, no miles on it, will last longer
cons: will cost around 4-5k more

What do yall who know a bit more think? is it worth the extra 4-5k to have a car with no miles on it?
