What wulf said may be how they do it in CO. Out here the ones in use are stop n go along their service area. Our streets run just under 1 mi long per.
You wouldn't know how they were driven unless you knew their delivery route and vehicle history. For the money they might not be a bad deal, maybe.
With them being under 100K you'd not have a hard time dumping one, if it was more of a headache, than not.
