Bro Vitz 1.0L is a good car (I myself own one), but not comparable to City, which is a Sedan and has more powerful engines.
City sell kar k Vitz laina, is like; "Koori waich k Majj ley laina" (in English, it means buy a cow after selling a horse, i.e. Bewakuufi)
I would suggest to continue with City, rest, your money, your choice!
