A used car engine is safe if it was worked on by a certified professional. That way you know you will get quality added to the engine for optimal performance.
If a used car is sold as is, I would be a little leary of the car. If they offer a 30 day warrenty on the car, I would takw it out on a test drive and stop by a mechanic (garage) and have them check it out for you to see if they find and noticeable problems. If you do that I would say they are safe.
it is safe to drive slower because you could get in a car accident if you drive really fast
