You asked the same type question in your previous post and somehow you don't understand the difference between buying AS IS and CERTIFIED. after study.
I really don't with my 2 finger typing sit here all day trying to make you understand a question where buying certified is more safe - and then again buying non certified for less money could be a better deal,,, I would really have to view your choice of vehicle to make a proper comment,,, and that's why I asked for a link in your first post.
If you want email with a phone # and best time to call,,, and I will walk you through the process to ensure not getting a lemon.
