Re: low milage vs. high milage
I'd personally say for SyTy's that - at this time - under 50k is low, 50-100k is average, above 100k is high. If you're looking for a "low mileage vehicle" from 91-93, then yes, 100k is probably on the lower end. However, when you take into consideration the average mileage of SyTy's, the 50k/100k holds pretty true to divide the population into thirds.
As mentioned elsewhere, mileage is only a number. I've seen trucks with under 1k miles that looked pretty rough, and conversely Bob Galla's Ty has ~100k on it (all original paint except cowl hood) and was just in GMHTP and wins awards everywhere it goes. Ownership can "add or subtract mileage" if you will.
Just my :2cents:
