The pedal wear check is an excellent idea. It varies from car to car, but with 30K miles it should be very slight, and at that mileage I can imagine that it might even have the OEM tires though they would be well worn, and a replacement set should look near new.

If records are available, they is the best way to verify logical mileage accumulation, but in the absense of records, wear and tear are the only way to verify. Well kept, low mileage cars are out there, and the overall condition of the car should match the low the mileage.
