hello;

I am planning to buy an 2007 altima hybid 60.000 km. Genral warranty on it experis in 6 months. I would like to ask a question. I d really appreciate if you can help me out. can you take your hybrid car to a regular mechanic for non hybrid issues? does an hybrid car has a fuel and hybrid engine as separate units or the engine it has is totally different type lets say like a combined one. the reason that i am asking this is to consider to purchase additional dealer warrant when ibuy a second hand.
Thank you
