Regular gas is only "bad" if you have an engine and ECU incapable of adjusting to the octane difference. Once in a while is okay.

I think what OP is implying is that if the salesman didn't even know it took premium then chances are as a used car its seen more than one fill up with regular fuel... Even then its hard to say whether the previous owner did the same, I doubt the engine would be too happy about being fed 87 its whole life...
