Wa Alaikum Salam Bro. Buy brand new Corolla.
I won't recommend and consider it a wise decision to buy a used JDM, Hybrid vehicle, above 21-23 lac PKR, especially when it's out-of market option like Grace, etc.
If you are interested in buying a used JDM, 1500 cc, hybrid vehicle, prefer Aqua, Fit, Vezel and Juke (priority / budget wise) which are "Market ki gaarian" or Prius (1800 cc), otherwise, out-of market options become headache if any problem arises.
