So.. I love my husband..

but yeah.. we went and test drove a beautiful PT..
2002 PT Cruiser limited
there was a few issues:
windshield chip (or internal crack or whatever it's called)
small ding under chrysler emblem on back
small rust mark on hood right above grill
plus sides:
new tires
new brakes
new/rebuilt transmission
new sparks etc
500 dollar grill
So after we test drove it, Hubby took it upon himself to offer the guy 6,000 dollars.
My question is, are we stuck on that? Or are we going to look like total jerks if we call them back and try to renegotiate it? I really don't want to pay over 5,800 for it... Thoughts??
