I will vote for Brand New Swift DLX (White Color - I prefer white color - U can buy the color u like - no Hard Feelings On Color )
Now, why i am voting for Swift..... ?
I had 2006 Vitz - Bought in Jan 2009 - Push Button Start - when i bought it was 13,000 Km...(that was fake for sure). I kept the car for 3 years...and sold it. Why?
Well first of all, the car was almost 5 years OLD now and with time wear and tear happens. Not many good mechanics are arround who car trace the issues if any happend in the car.
keyless entry and push start is not what a local mechanic can handle...replacement cost of keyless entry is over Rs.30,000 if you lose the unit. Push Start Solinoid is also expensive i.e. over Rs.25,000
Please don't compare 2007 Vitz with Brand New Swift.... Brand new swift will give u peace of mind for atleast 3 - 4 years if you look after it well.
Brand new is always brand new- and used item are always used just think about new and used.
Vitz parts are easily available in the market now. But brand new parts of Vitz are very very expensive. Toyota is selling Vitz Ac Compressor for Rs. 80,000 ( Eighty Thousand - yes just for teh compressor) . Side mirros for vitz are over Rs. 35,000 for the pair.
Again you can buy a used Vitz and buy used parts from Bilal Ganj - Lahore....but used is used
My sincere advice will be brand new swift dlx - white color and enjoy trouble free ride for 3 - 4 years easily. All parts are easily available, at a cheaper rate.
