Vitz is a good car but you have to search hard to buy any used car that’s in great condition. Be prepared to reject a lot of them, most sellers will lie to their teeth like it’s full genuine , no paint etc.
As it’s imported, make sure the verified auction sheet says Grade 4 to 5. Nothing below. Though I would prefer local cars as it’s much easier to source parts. For Japs it’s a nightmare.
Do take inspection service. No matter its pakwheels or OLX or some other, make sure they test the vehicle thoroughly.
Paint should be checked with paint checker PEN or through the digital gauge. You can do it on your own too, just order a paint test pen from Daraz or any store it is a life saver and will immediately tell you if any panel is repainted.
Thoroughly check the suspension, after visual do a test drive on potholes there should be no noise.
Check for any oil leaks like engine oil, transmission oil, Radiator functionality n make sure they use a coolant rather than water.
Presence of cat converter.
No adverse computer codes.
It’s a learning experience but the inspection service alongside your judgment will definitely get you a good car.
Just have to search a lot.
