I would say the bigger question is has it been maintained properly? I will admit that's a low LMPG, but there could be several causes. One, yeah he possibly just drove it hard, though the lowest mileage I've ever been able to get was 45mpg while cruising around 90 on a mostly up hill drive which included a 6% grade for several miles (man that was a fun drive though). Or secondly perhaps he valued his AC and used full auto AC (disables auto stop) in mostly city driving. This I wouldn't count as so bad, if anything it'd be good for the batteries.
If there is anothe car out there then perhaps this one should be passed on, but there are several unknown factors at play here. Also, does it have the correct Potenza RE92 165 tires on it? I once saw an Insight with a similar LMPG where they'd put some cheapo 185 size tires on which were underinflated. I drove it briefly a few yards (this was at a dealer car auction so I did it when no one was looking) and I could feel how much resistance this seemingly little thing made.
