Which one listed is $100K? One of those '69 convertibles isn't an "R" or "Q" code, is it?
If so, I do have something that might be of interest in a partial trade!
In reality, things that I would consider going away (in trade) are:
(1) 1967 XR7/GT Cougar (FE-390) 4 speed...1 of 905, according to Marti report. Not a project. No rust; paint 4 years or so old. Runs and drives great. Iverness (very dark) Green with Saddle interior (tan). $17,500 or so.
(2) 1968 289/AT Mustang Coupe 95% original car; 68K miles believed to be original. Driver car. Gold w/black vinyl top and gold interior. $7,500 or so.
(3) 1969 F-code/AT Mustang Coupe. Tired. Getting the brakes working now, so doesn't currently drive. Aztec Aqua with black standard interior. As-is $3,000 or so.
I am in western Oregon, so shipping is an issue! Ideally, I would like to trade all #3 above, for one car of similar value, around $28K. I currently have WAY too many cars and would like to get down to a more manageable number. I'm not really into getting something needing much (any) rust repair as I have to farm that out for big $$$. I also have to farm out paint work, but I can tolerate pretty sad-looking paint, if it's on the right car...
