I m going Multan from Islamabad - 600 KM today..
will let u know the experience....Vitz 2007 ..1300cc VVTI
otherwise i travelled same route with my vitz 2006 in 2011...I find it very comfortable and stable car for long drive..
i love it drive on long drive...
i never seen any vitz stopped on motorway due to heat or mechnical issues....like local Carz
i think
Japanies Vitz is a gift for pakistani market where ppl only think about re sale value rather then thousands of options available in vitz family
