there is hardly a mechanic around who really knows what he s doing when it comes to repairing prius.
prius is a good ride but not too comfortable. i had a prius for test driving for 3 days and i was comparing it with a reborn. low ground clearance (and i mean really low)
if you want to buy her just coz you like her, do go for it. i believe, bande ko khurak ho rahi ho to khurak karni chahiye, lol
battery is not a big risk. they dont die that easily and used ones are available around 70k imported from dubai.
spares are expensive but all cars have expensive maintenance these days (sedans)
like lea300 said, buy a car with ORIGINAL less miles on the clock. you will be happy.
BUT if Allah forbid, a fault develops in it, it MAY NOT be easy to get it cleared.
