As you have tp cover long distances on daily basis so please don't put your money for craps but just go for a better bike as bro Amjad told. You have option to buy a 2010-11 model CHONDA in around Rs.25000/-
yesterday, chiken shop wala in my town told me that he sold a suzuki sprinter in 22K to a showroom owner (Sajid motors - opposite suzuki showroom GT Road gujranwala) whose engine was in good condition but body required some maintenace work. He bought the same around 4 years back in 40k. So you may think of getting a bike whose Engine is in good condition then baqi ap ko thora budget required ho ga for repair.
However, if 80Km+ is your daily usage then I agree with Racer7 bro and Amjad bro ke ap zara budget increase kar ke koi achi Chonda(ya better Suzuki sprinter) le lein.
