- Checking the auction grade?
Doesnt count one bit,get the car checked.
- Buy registered or unregistered one?
With your range of 550k best option is a reg 2003 model FL
- How to check the cars condition, as mostly the dealers make them tip top before selling?
Take a denter/painter with you and a mechanic to get it checked,or a few friends,test drive the car properly check each and everything.
- Where to look for it, in Lahore from where can i find a good VITZ?
No idea abt that one
- Should i prefer automatic or manual one, is manual easily available, as the car will be run on CNG.
Manual hard to find and more expensive,CNG works fine on auto so dont worry abt it
One tip from me,dont look at the milage of the car,check the interior,stearing,dash tires body etc to get a feel of the car.Milage can be and will be tempered.
