Marlin

Just joined and first post. Been trying to get a feel for the value of my dads Mustang. Would appreciate any expertise on Mustang values.
My dad purchased our 67 Mustang hypo 289 fastback K code new from the Ford dealership in Portrland OR. It is candy apple red with the white gt stripes along bottom. No a/c, power steering or console. 4 speed standard trans. Original hypo 289 engine (runs well) and original 4 speed transmission. Car runs very well. Paint is original and in very good condition with some rock chips. Original black interior carpet and seat covers with exception of drivers seat cover. Original am/fm radio. Original hub caps. 90,800 original miles. Car is in very good condition and has been garage kept most of its life with a car cover on.
I know there was only around 240 or so 67 K code fast backs made and can't imagine many are left. Especially in this condition. Would like to hear estimates on value. Do not know how to attach photos on the blog but can e-mail pics.
thanks in advance. Kirk.
