What affects value most when buying or selling
The main drivers of price for a 2006 GS 300 are:
- Maintenance history and service records
- Accident history and title status
- Mileage and wear on major components (engine, transmission, suspension)
- Location and local demand for older luxury sedans

Before committing to a purchase, consider a thorough inspection by a qualified mechanic and obtain a vehicle history report to understand any hidden issues that could affect value.
Buying considerations and quick tips
To optimize value, focus on documenting maintenance, addressing noticeable issues, and negotiating based on verifiable condition rather than asking price alone.

- Compare multiple listings in your area to gauge current market pricing.
Armed with data from valuation tools and a careful inspection, you can set a realistic expectation and negotiate a fair price.
