Almost all of those prices are reasonable. Damn near 30 year old cars in perfect condition, all original un-restored, and less than 50,000 miles? The only unreasonable ones are the ???? miles car and the the cheapest one with 162,000 miles and restoration work. 32,000 miles for $10,000 very reasonable. ????? miles for $16,500 screw that! 19,000 miles for $15,000 very reasonable. 42,000 miles for $11,000 is a bit pricy unless rare options. Is a blue Auto rare for 1988? 163,000 miles for $6,900 restored, not stock, high miles... but in great condition. Probably the least reasonable one listed here even though it is the least expensive. Anything over 50,000 miles or aftermarket parts (even audio equipment) isn't a collector car unless returned to stock and fully restored... but bone stock, un-restored, perfect condition and under 20,000 miles? Buy it and store it! I almost felt guilty about buying a 57,000 mile 1984 for $2,500 but that didn't stop me from handing over the $$$. Keith
