Preferring Honda PCX/ADV150 over Yamaha NMAX if buying bnew.

Just because the Yamaha cannot be bought bought from the dealer on cash.
They wont say it outright though, instead they will say there's a waiting list/period that they cant say how long.

Otherwise, they are pretty much equal. NMAX is bit faster, PCX/ADV150 better fuel mileage and larger utility box.
