I have decided to buy an Oriel Prosmatec (2011-2012 old shape. This is the first time I am buying a car on my own and would request urgent guidance from the members especially on the following points:

1. How to ensure that the warranty is still valid. Do I need to go to dealership, if yes, then do sellers generally help or you got to insist?

2. How to ensure that the parts and paint is genuine.

3. Fair price range for 2011 and 2012 Oriel Pros with normal mileage.

4. General negotiation and other desired tips.

I know I am asking a lot but where else can i go for help?
