What are the best years for Lexus Rx300?


The best Lexus RX 300 years are generally considered to be the 2001-2003 models because they were produced after a mid-cycle refresh and benefited from a more reliable 3.0L V6 engine with a four-speed automatic transmission. These years represent the peak of the first-generation RX 300's development and refinement, making them a good balance of reliability and features.
 
Why these years are recommended

  • Model year improvements: The 2001 model year received updates such as new styling for the grille, taillights, and exterior trim, along with optional HID headlights and a navigation package. 
  • Reliable engine: The 3.0-liter V6 engine (1MZ-FE) in these models is known for its durability, as long as routine maintenance, such as timing belt replacements, is performed correctly. 
  • Smooth ride: The RX 300 is praised for its smooth and quiet ride, making it a comfortable choice for daily driving and long trips. 
  • High reliability ratings: Owners consistently report high reliability and low maintenance costs for these models, with many cars reaching high mileage with minimal issues. 

What to watch out for
  • Engine sludge: The engine is susceptible to sludge buildup if oil changes are neglected, so it's crucial to check the service history for a record of regular oil changes. 
  • Dash cracking: Some models from the first generation can experience dash cracking issues, so check the condition of the dashboard carefully. 
  • Rust: The frame can rust out over time, especially in areas with a lot of road salt, so inspect the underbody for any signs of significant corrosion. 

A note on other models
  • If you are not set on the RX 300, the RX 330 (2004-2006) and the RX 350 (2007-present) are also very reliable options that offer modern features and improved performance. 
  • The second generation (RX 330) can be a great value, with 2006 and 2007 being particularly good years due to their high reliability ratings and inclusion of a timing chain, which eliminates the need for timing belt replacements. 



How much is a 1999 Lexus Rx300 worth today?


The price for a 1999 Lexus RX 300 typically ranges from approximately $2,400 to $6,500, with an average price of around $4,000, depending on factors like mileage, condition, and specific features.

What is the common fault with the Lexus Rx300?
