Is Lexus IS-F worth buying?

Yes, it can be worth buying for a buyer who wants a rare, high-revving V8 Lexus with engaging performance, but expect higher maintenance costs and older technology.

The IS-F, Lexus's performance-focused variant of the IS sedan, was built from 2008 through 2014. It pairs a 5.0-liter V8 with a rear-wheel-drive chassis and a sport-tuned suspension to deliver a spirited driving experience. In today’s used-car market, prices vary widely based on mileage, condition, and maintenance history, and buyers should weigh older tech and potentially higher upkeep against the car’s distinctive character and Lexus reliability.

Performance and driving dynamics

The IS-F is built to deliver a vigorous, driver-focused experience rather than a supremely refined daily commuter. Here are the core performance traits to know.

Key specifications and feel

• Engine: 5.0-liter V8 (2UR-GSE) with about 416 horsepower and 371 lb-ft of torque


• Transmission: 8-speed automatic with paddle shifters


• Drivetrain: Rear-wheel drive with a performance-tuned setup


• Performance figures: 0-60 mph in roughly 4.6 seconds; top speed near 170 mph (varying by model year and tires)


• Chassis and feel: Sharp, communicative steering and a sport-tuned suspension; strong Brembo brakes for confident stopping


• Sound and character: Distinctive V8 exhaust notes that stand out in the segment


• Weight: About 4,000 pounds, which helps stability but can reduce agility vs. lighter peers

In daily driving, the IS-F can feel more focused and noisy than many modern rivals. It excels on a winding road or track day, but the trade-off is a firmer ride and more cabin intrusion than you might expect from a traditional luxury sedan.

Reliability, maintenance, and ownership costs

As a high-performance variant on an older Lexus platform, the IS-F combines Lexus reliability with performance-oriented wear. Buyers should budget for higher maintenance, especially as the car ages.

• Fuel economy: roughly 16-18 mpg in city driving and 23-25 mpg on highways; real-world results depend heavily on driving style


• Reliability: Generally solid for a V8 Lexus, but components age and can be costly to replace; seek a well-documented service history


• Common wear items: cooling-system components (radiator, hoses, water pump), suspension bushings, tires, and brakes typically show wear sooner due to performance focus


• Maintenance costs: higher than average for a non-performance luxury sedan; parts and specialty labor can add up, especially if a full cooling, exhaust, or drivetrain service is needed


• Ownership considerations: insurance can be higher for a performance model; aftermarket maintenance discounts exist, but expertise on the IS-F is essential for accurate diagnosis and repair

Overall, the IS-F can be dependable with attentive maintenance, but buyers should be prepared for premium upkeep and the possibility of costlier repairs as the car ages. A model with strong service records and limited corrosion or accident history tends to fare best in the long run.

Market value, buying tips, and what to check before purchase

The used-market value for the IS-F varies with mileage, condition, and service history. As of 2025, typical asking prices hover in a broad range, with low-mileage, well-documented examples commanding the higher end.

1. Determine a realistic budget and compare market values from multiple sources (Kelley Blue Book, Hagerty, Carfax pricing, and local listings) to understand fair pricing for your area.


2. Prioritize a thorough pre-purchase inspection (PPI) by a shop familiar with Lexus V8 performance cars. Check for oil and coolant leaks, listen for exhaust and engine anomalies, and verify the condition of the transmission and differential.


3. Review maintenance history: look for documented cooling-system work, brake and tire replacements, timing-chain/drive components if applicable, and evidence of regular fluid services.


4. Inspect for rust, frame damage, and body/paint issues; confirm that recalls have been addressed and verify the VIN against service campaigns.


5. Test drive with attention to a smooth transmission, steady power delivery, solid braking, and absence of abnormal noises or vibrations; ensure the steering feel matches your expectations.


6. Consider total ownership cost and reliability: plan for potentially higher insurance, fuel, and maintenance expenses relative to non-performance luxury sedans.

With a clean history, solid maintenance, and a comprehensive inspection, the IS-F can be a compelling choice for enthusiasts who want a rare, front-footed V8 Lexus with a distinctive character. Prices reflect its uniqueness and the costs of keeping an aging performance car on the road.

Bottom line / Summary

The Lexus IS-F remains an appealing option for buyers who value a rare, high-performance Lexus with a muscular V8 and a practical four-door layout. It is not the most technologically advanced or comfortable option by today’s standards, and ownership can be costly as the car ages. If you find a well-documented example at a fair price and you’re prepared for the maintenance realities, the IS-F offers a distinctive and rewarding driving experience that few rivals can match in terms of character.

Is the Lexus IS F reliable?

The Lexus IS-F is considered very reliable, largely due to its robust naturally aspirated 5.0L V8 engine and its durable build, which often leads to a strong resale value. While most owners report few major issues, common maintenance concerns can include potential leaks from the valley plate or plastic and rubber hoses in the engine bay. To ensure long-term reliability, proper maintenance and a pre-purchase inspection are recommended, especially to check if the car has been excessively modified.
