No hard feelings but, puting emulator and advancer in dashboard is not a new thing, Two years warentee too, Landi Renzo is available in 9100/- everywhere, Brazilian cylinder (55wl) 17000 - 17500/- complete installation from 32000/- to 35000/- depends on the brand of electronics.
No Toyota Authorise dealer can give you after sale service in Pakistan.
On top of it Toyota Dealership is not authorise to do installation of cng kits. You can check it with OGRA. So how can they give you any gaurentee.
