Im surprised and impressed with all the nice improvements on the 997, such as tilting and telescoping steering wheel, DVD nav, integrated phone kit, homelink, control ***** on the steering wheel, etc. What would a slightly used TTcab bring on trade in? Mine is silver, with natural gray leather, gray top, tip, lots of extra interior leather and paint, 1000 miles, perfect condition, MSRP was around 150k...Thanks in advance..
