Around here, they'd likely be listed for $1,500-$2,000 if the tires are good (and not just good tread depth- "good" as in balanced and roll smoothly. Many are now wise to the possibly defective "Brickstones"). Most similar ads for takeoffs in excellent condition with good tires start around $2,000 and seem to gradually drop to the $1,500 range with some of the lesser-desirable wheel/tire packages eventually selling for closer to $1,000.
