The resale value of the IS 300 can vary based on several factors.

The condition of the vehicle is crucial. A well-maintained IS 300 with low mileage and no major damages will have a higher resale value.

The model year also matters. Newer models tend to command better prices.

The vehicle's history, such as whether it's been in accidents or had major mechanical issues, significantly affects its value.

Options and features can boost the resale value. Popular features like advanced safety systems, upgraded audio, and premium interior trims can make the car more attractive to buyers.

Market demand plays a role too. If the IS 300 is in high demand in your area, you'll likely get a better resale price.

To maximize the resale value, keep detailed maintenance records, have the car serviced regularly, and keep the interior and exterior clean and in good condition. Also, be aware of market trends and price your car competitively when selling.
