The Lexus IS is a refined and reliable compact executive car that combines luxury with performance. When considering a used model, it is essential to check its history, condition, and specifications to ensure you make a wise investment. This guide provides a full checklist to help you through the buying process.
Understanding the Lexus IS Range
The Lexus IS has undergone several generations since its introduction in 1998, with each offering different features and specifications. The most recent models include the IS 200t, IS 300h, and IS 350, each catering to varying preferences for performance and efficiency. Familiarising yourself with the specific model year and trim levels can help you identify the best fit for your needs.
When exploring the range, consider the engine options available. The IS 200t features a turbocharged petrol engine, while the IS 300h is a hybrid, combining petrol and electric power for improved fuel efficiency. The IS 350 offers a more powerful V6 engine, appealing to those seeking a sportier drive.
Checking the Vehicle History
Before purchasing a used Lexus IS, it is crucial to obtain a comprehensive vehicle history report. This report should include information about previous owners, service history, and any recorded accidents. A well-documented history can indicate how well the car has been maintained and whether it has been involved in any significant incidents.
You can also check for outstanding finance or insurance write-offs. The DVSA MOT data can provide insights into the car’s past MOT results, including any advisories or failures, which may highlight potential issues. Additionally, verifying the Vehicle Identification Number (VIN) against the report ensures the car’s identity matches the documentation.
Inspecting the Exterior and Interior
A thorough inspection of the car’s exterior and interior is essential to assess its condition. Look for signs of rust, dents, or scratches on the bodywork, as these can indicate neglect or previous accidents. Pay particular attention to the condition of the paintwork and any signs of poor repairs.
Inside the car, check the upholstery for wear and tear, ensuring that all electronic features, such as the infotainment system and climate control, are functioning correctly. The quality of materials used in the Lexus IS is generally high, so any significant wear may be a red flag.
Test Driving the Lexus IS
A test drive is a critical step in the buying process, allowing you to evaluate the car’s performance and comfort. Pay attention to how the car handles, accelerates, and brakes. Listen for any unusual noises from the engine or suspension, which could indicate underlying issues.
During the test drive, assess the comfort of the seats and the overall driving experience. The Lexus IS is known for its smooth ride and quiet cabin, so any deviations from this may warrant further investigation. Additionally, try out various driving modes if available, as this can showcase the car’s versatility.
Reviewing Maintenance and Service Records
Regular maintenance is vital for the longevity of any vehicle, and the Lexus IS is no exception. Review the service history to ensure the car has received timely maintenance, including oil changes, brake inspections, and tyre rotations. A well-maintained vehicle is likely to perform better and have fewer issues down the line.
Check whether the car has been serviced at a Lexus dealership or a reputable garage. Using genuine parts and following manufacturer guidelines can significantly impact the car’s reliability. If the service records are incomplete or missing, consider it a potential red flag.
Understanding Common Issues and Reliability
While the Lexus IS is generally regarded as a reliable vehicle, being aware of common issues can help you decide with confidence. Some owners have reported problems with the infotainment system, particularly in older models. Additionally, hybrid models may experience battery-related concerns as they age.
Consulting resources like the Honest John reliability index can provide insights into the experiences of other Lexus IS owners. This information can help you identify potential issues and assess whether a specific model year is worth considering.
Final Considerations Before Purchase
Before finalising your purchase, ensure you have all necessary documentation, including the V5C registration document and a valid MOT certificate. If possible, consider having the car inspected by a professional mechanic to uncover any hidden issues.
Also, factor in the cost of insurance, road tax, and potential repairs when budgeting for your Lexus IS. Understanding these costs can help you gauge the overall affordability of the vehicle. Finally, be prepared to negotiate based on your findings during the inspection and test drive, as this can help you secure a better deal.
