I am also currently looking for a reasonable Sedan in reasonable price (as I have recently sold my Vitz), but no luck yet.
The cars which seemed good, were priced extremely high, did not got "hausla" to call the sellers.
The ones with reasonable prices, were found severely abused, accidented, etc. when enquired telephonic.
Came across 02-03 cars ads, seemed reasonable, made calls, and the sellers said that the cars have just been sold.
So Yes! Sale-purchase is in full swing. And even if offices are closed, still bio-metric facility from Nadra E Sahulat Marakiz is there. If it isn't, then Stamp papers are there to make sale-purchase deeds, transfer / sale agreements, etc.
