In all the discussion here, I think it should be pointed out that it is probably prudent to avoid buying a former daily rental.
Many states require dealers to disclose to consumers that the car was a former daily rental.
The reason(s) for this include the abuse the vehicle may suffer (its not my car attitude of renters), a drivers usual unfamiliarity with an areas road conditions/hazards (like hitting those "sleeping police" in the DR at 50 mph....I have seen that one lots of times), lack of or the foregoing of maintenance, etc.
Note: This is not to be confused with a leased vehicle. Those tend to be cared for far better than their daily rental couisins.
Respectfully,
