Lexus is Excellent car. actually i does not need any maintenance if handled carefully, driving safely, maintaining well... even high mileage also does not effect its engine..serious repair or replacement is only required in case of accident/or other serious damage happened.. in that case its maintenance is expensive compared to Toyota/Nissan. i suggest go for it if you believe in conscious and safe driving...because if you drive Lexus you will feel heavenly experience.. if you go for long drive you will feel you are driving on waters.
