To estimate the price of the 2016 Lexus IS350 Elite (Mid) with 156000 km mileage, I considered the listed prices of similar cars. The closest match is a 2016 Lexus IS350 Elite (Mid) with the same mileage listed for AED 81000. Other relevant listings include a 2017 Lexus IS350 Elite (Mid) with 130000 km listed for AED 85000, and a 2017 Lexus IS350 Premier (Base) with 165000 km listed for AED 69500. Given the condition and mileage of the target car, I adjusted the price slightly lower than the closest match to account for potential negotiation and market conditions.
