How much is a 2008 Lexus RX400h worth?

A 2008 Lexus RX 400h is worth approximately $5,000 to $7,000, with the exact value depending on its condition, mileage, and local market. Prices can range from around $2,000 for high-mileage vehicles to over $10,000 for one in exceptional condition with low mileage.
 
Factors that influence value

• Mileage: A vehicle with very low mileage will be worth more, while a high-mileage one will be worth less. 
• Condition: A vehicle with a clean history, no accidents, and in good mechanical and cosmetic condition will command a higher price. 
• Market: The value can vary based on your specific location and what others are willing to pay in your area. 
• Features: Options like a power liftgate or premium audio can slightly increase the value. 

How to determine the value

• Use online appraisal tools from sites like Edmunds, Kelley Blue Book, and J.D. Power to get an estimate based on your vehicle's specific details. 
• Check local listings on sites like Cars.com and TrueCar to see what similar vehicles are selling for in your area. 
• Get a professional pre-purchase inspection to uncover any potential issues that could lower the value.

How many miles will a 2009 Lexus RX 350 last?

A 2009 Lexus RX 350 can last between 250,000 and 350,000 miles with proper maintenance, but many owners report reaching 300,000 miles or more. Regular service, such as timely oil changes and other fluid checks, is crucial to achieving this long lifespan.
 
Factors influencing longevity

• Reliability: The RX 350 is known for its reliability, which is helped by its proven powertrain and relatively simple all-wheel-drive system. 
• Maintenance:
  • Oil changes: Consistent oil changes with synthetic oil can significantly extend the engine's life. 
  • Transmission fluid: Replacing the transmission fluid every 60,000 miles is recommended, as using "lifetime fluid" can be detrimental. 
  • Other fluids: Regular coolant flushes and suspension checks also contribute to a longer life. 
• Repairs: While this model has a low-to-average frequency of major repairs, it's important to be prepared for repairs that may be needed as the vehicle ages, especially after 100,000 miles. 

What to expect

• Overall lifespan: Expect to get 250,000 to 300,000+ miles from a well-maintained 2009 RX 350. 
• Ages and costs: The model year is less important than its maintenance history. A car that has been regularly serviced will last longer than one that has been neglected, regardless of its age.
