How can I trade my 1985 Jaguar XJ6 and 1996 Dodge Intrepid for a newer vehicle?

The Jaguar is a 1985 Jaguar XJ6 Van den plaus Gold in color runs and driveable and is currently in the shop for break and fuel lines. The car needs restoration and a new ignition but runs and is drivable. I also have a list of items that need attention. The vehicle is currently registered and road capable in Wisconsin 120,000 miles. The intrepid is my regular drive blue in color and has about 160,000 miles but runs very well. has cosmetic flaws but everything works.

I really love both vehicles but want to trade them to someone for a newer car better on gas like an older bmw 300 series or mitsubishi or mercury cougar 1999 or newer. any suggestions? Or where to look? both title clear..
