I'd say that 28 lakhs would be an overkill for a 37k driven. But again that is an Islamabad registered car, so prices might differ... An exact same car would sell for 26-27 in Karachi.

Usually, black cars are cheaper than white cars, therefore, it should've been placed cheaper than a Super White Corolla.
