At the moment the resale part is correct but doesn't just mean we should buy a obsolete car from 1980s just because of resale. It is a trade off. Let's compare Cultus with similar price tag.
Paksuzuki Cultus (similar price to V2 I am not considering Swift as it is much more expensive)
Pros
-Good Resale
-Parts easily Available
Cons
-Obsolete vehicle (phased out all over the world ages ago)
-Poor Built Quality
-Ancient engine techology
-Barely meets Euro 2 emission
-No Airbags
-No Abs
-Poor tire quality
-unimpressive fuel consumption despite being 1000cc
V2
Cons
-Resale
-Parts not that easily available (although many Vitz part fit into the engine components)
Pros
-Relatively newer technology
-ABS + EBD (from Bosch)
-Dual Airbags (not even available in Altis 1.8 !! only in Civic)
-Better Quality
-Euro 4 compliant (only civic and city are Euro 4 compliant in local assembled cars)
-Better tire quality
If someone is going to keep the car for a long time 5-10 years. The safety value you get out of the car far outweighs Paksuzuki lineup. Always remember resale wont protect anyone's life in case of collision.
Even if we do compare Swift might lose invoice value of 50-100k. But due to it being 1328 cc The WHT on a New Swift is 100,000 PKR for Non-Filers and 50,000 for Filers. Furthermore token is also more expensive. V2 falls under 1300 cc therefore enjoys some tax benefits and lower registration costs. When swift is being sold you can't get price above invoice and cover for your WHT and registration. Even a used Islamabad registered Swift will incur a transfer fee for 50,000 rs or so (have to confirm exact amount) for non-filters as it is above 1300cc because government of Pakistan thinks a 1300cc+ car is a luxury 
We have a new company and FAW is starting assembly of local V2 and is expected to Introduce automatic V2 soon. I agree V2 is no stunning breakthrough but we don't have any other options at the moment. Only one small car assembler exists and FAW is the only company willing to change that. PML-N led government handed complete contract of cab scheme vehicles to PakSuzuki without even considering anything else. The same thing happened that led to ADAM revo the government gave them assurances but later never supported them and handed out all contracts to Paksuzuki (which by the way sends all its profits back to its HQ in Japan instead of reinvesting in new technology in Pakistan).
If the government just gives another player one contract for 5000 vehicles or so it will solve the resale issue as well to a good extent.
