I am interested but you should know that prices of used vitz have gone down drammatically. Babar Omar sold red vitz late 2000 (12th month, on papers it is 2001) fresh import for 430K.
Since your car is already on road, it has dropped few more thousand. I can offer you 430K cash instantly. By the way you have a better offer, usman666 offered you 450K, if he is serious, sell it to him.
575K is way too expensive. Let me know because I have to source out within a week for myself.
