Help in buying a new Grand Marquis

My parents want to take advantage of the 0% for 60 months in getting a new
Grand Marquis LS Ultimate. They want to get side/passenger airbags with the
handing package, the heated front cushion seats..after building it it came
out to about $32,220. What can expect to pay for it...and where shoud I go
any tips? Oh and they want it have it in the next few weeks!
I live the NYC metro Area....

Thanx for any help!

I've had 3 Marquis's, 98, 00, and 01. I bought all of them a year old with low miles...after they'd lost 40%+ of their original value. My advice is to let someone else pay for the first year depreciation, then you pick
the practically new car for low dollar on a pre-owned car lot.
