We need to know which model of Citori you're considering ... there are about 25 models ....??
If you're looking at a new or older version of the Citori Lightning ...that lists new now for around $ 1,869 / selling for around $ 1,600 - $ 1,700 ...maybe the shop is making you a deal / maybe not ...

I think in general, the Citori Lightning is an entry level Citori - and while a very strong gun mechanically - it has a lot of drop at comb and at the heel / and its a little light - consequently doesn't fit most shooters very well / at least without some comb pads / or maybe an adjustable butt plate ( Jones pad..).
In general, a decision between the Citori Lightning vs a Superposed - go with the superposed.... But $ 699 for a superposed makes me a little nervous ( its pretty cheap ) ...so the issues may be more than just cosmetic. On the other hand - a new in the box Citori Lightning - is worth more than $1,000 too ...so something isn't right there either.
I'd suggest you visit some other shops - compare what they have / try and get out to a gun club - get a better feel for the Citori lineup of guns / you'll probably see a number of different models out there - the XS Skeet, the 625 series, the XT, the Lightning ...etc ...
Personally, the Citori XS Skeet - with the adj comb and 30" barrels - is one of the most versatile guns they make / because it has so many built in adjustments - and characteristics - it will fit a lot of shooters. But the Citori XS Skeet now is listing new for around $ 3,300 / selling for about $ 3,000 probably ....

and I'm not trying to rain on your parade / only educate you that just because its a "Citori" -- doesn't mean all Citori's are created equal / or as adjustable / or will "Fit" all shooters .... Its not just the fancier wood on the XS Skeet that makes it sell for $ 3,000 ....
So you need to learn a little more about both guns you're considering - before we can really help you .../ the different models / what's out there on the used market ...
Just a note -- but a friend of my son's - just bought a used Citori Lightning - made in 1986 ( 24 yrs old ) .../ 28", 12ga / and it has the original Invector screw in chokes - not the newer Invector Plus. It has a number of scratches on it / handling marks - no case, no extra choke tubes ...and in my area, he was very lucky to get that gun for $ 750. Extra screw in chokes are about $ 40 each / a hard case is another $ 200 -- so he's going to get about $ 1,250 tied up in that gun before he even shoots it .... In 1986 / that gun sold new for around $ 600 .... I still think he made a decent deal / but its not the Citori XS Skeet model either ....
