+1 on Edmunds, >$16K is 'out there' at present market but hard to say without seeing it - dealers don't give a terrific view of the X, so a look-see should tell more. Low mileage is a definite plus and if they have records to prove "all services done", you're closer, u know the deal, $16K if it is obviously a grocery getter at 7k mile/yr -could- be a bargain..

My experience is that Females that like the e53, Really Like the e53, so this may be a Moot discussion, heheh..
Can you talk her into an Indy Inspection and does the dealer offer a warranty that you are allowed to READ?
personally, I run, do not walk, from a dealer on a car this old..
show her fleabay, at least she can get an idea of what's out there and price-ranges..

(disagree on the overpaid for '04 comment, unless you have seen the X and met the previous owner - mileage is Nothing compared to owner and history)
