Seattle Used 2006 Chrysler Crossfire Limited Tacoma

Don't think I can post a link, but the car I am looking at is:
2006 LTD Coupe. 55k miles manual 6 speed. Dark red exterior, two tone gray leather interior. Car is in great condition, 1 owner, purchased initially in late summer 2007. (if you are interested or feeling super helpful, car can be found on Larson Automotive Cadillac Saab Fife (Tacoma), WA. IT IS THE ONLY X-fire in their used inventory.

They say retail value is 15,995, they are asking 13,998. Based on NADA and kbb, these numbers seem too high- I will get them to come down as much as I can. Going to dealer 9:30 am. Already test drove car today and loved it.

1) any common problems to look for (or expect in the future?

2) I noticed condensation inside rear window... Normal? If not what are potential causes and are they serious?

3) any thoughts what price I should shoot for.

I would truly appreciate any thoughts or advice. I currently own a 2003 Nissan Murano I bought off the showroom floor 8.5 years ago. It has every available factory add-on plus some aftermarket 20" wheels. The Murano forum I belong to has always been a great source of advice and information; I can only hope Crossfire owners are as eager to help newbies as we all have been with the MO (Murano).

My son is finally graduating HS and moving out, so back toa two seater - finally!

Before the MO I had a 1998 Sebring (owned 1999-2003), a 1993 Jeep Cherokee LTD (1993-1999), and before that of course my beloved Nissan Z.

X-fire seems like a better value for the $ and I think it looks way better & drives better I have also looked at the Mercedes CLK & SLK.

thanks I'm advance!
