Wa Alaikum Salam. Bro regarding price, you can check pakwheels or other similar websites. You can also give a visit to market to get idea.
Just filter out Toyota Passo, model year: 2007 and check min. and max. prices on pakwheels. Go through ads description to find out more. Draw a rough comparison. Shortlist 01-02 cars. Get them carsured / inspected by pakwheels car inspection service. Select and finalize 01 car after max. bargaining / negotiation and buy it.
