Actually I suspect the Kirkham simple doesn't show well in the pictures as opposed to has more miles than indicated. Take the tires for instance, buying Goodyear Bill Boards is a bit of a crap shoot. You may well get some OLD tires, that are NEW in the sense they've never been mounted. That doesn't mean their not 10 years old all ready! You can't really judge from the lettering, which yellows within a year or so. For the letters to be scuffed it only takes ONE brush with the curb. Tread depth doesn't mean near as much as "weather cracking" due to age.
Dirty engine? I can relate! Man it's hard to keep those intakes clean. All it takes is ONE test and tune session to spill some gas on the intake and BAM, you gotta a stain. Not easy to remove. But there is a LOT that could have been done to make the engine area at least more presentable. Like wipe down the dist cap and the valve covers if nothing else! Vacuum the carpet would be a nice touch, DUH!
Even the body could use a good scotch brite going over. Anyway, clearly this a guy who is taking a beating on the car, is depressed and just wants it to go away. As such the buyer is in a good position to "low ball" the price. Then spruce it up with a little elbow grease to looking brand new with a DAY of work. Could be a real deal here. The best deals on a used car always happen with a car that is DIRTY, I love to buy them that way.
The Kirkham WILL NOT reach $85K, no way, not when it's "that dirty" in THIS market.
