Please do not go for a swapped engine Vitz, how is he running the Super CVT-i gearbox if he has the 2NZ-FE installed? The 2NZ-FE runs with a 4-speed automatic transmission not a Super CVT-i.
I would not suggest you to get it, he is asking way to much for a engine-swapped car.
BTW, why don't you raise your budget a little and buy a fresh import?
