I purchased a 2016 Infiniti Q50 certified last July 12,000 from Stuart Infiniti and after paying a premium for the vehicle I found out when bringing it to another dealership in Melbourne that the original tires which are run flats because there is NO spare where switched for cheap non-run flat tires. When I brought this back to the dealership attention I was told that the tires as long as they have tread are fine. They would not supply me in writing what a certified car from them contains. Clearly this was NEVER disclosed when I purchased the vehicle or I would have negotiated the price before buying. Bottom line avoid this dealership at all cost when thinking of purchasing a vehicle.
