Salam,
Yar the thing is, Vti is faster , better in control, better in looks and better in fuel consumption, but NOT A CAR FOR MONEY CONCIOUS PEOPLE. No resale , very expensive parts, very expensiv eto buy a zero meter, and wears out quickly, whereas corolla diesel is a car with very high resale, very low operational price, cheap parts and cheaper than the Vti if buying a Zero meter.
