Im thinking of buying a Ford Taurus GL 1994
With 54,000 miles
Motor 3.8 V6

Has anyone ever had this car…can you please give me some advice?
What are the important things to check on this car before buying it?
Does this car have any known defaults?

For the automatic transmission (normal use): How many miles can it normally take before having to change or repair the transmission?

Thanks!
p.s. the asking price is ,500

I have a 2004 Ford Taurus, only 45k miles, real nice condition. I want to get rid of it but dont seem to know how. I am looking for a place where i can list or sell the car for the closest to my asking price.
Things I've Tried:
-Local Community Paper
-Ebay

Can't seem to get autotrader.com to post my pics.
Any info at all is greatly appreciated!
