The Timeless Appeal of Older Cars
In an era where modern cars are packed with increasingly complex technology, many of which can fail without warning, older models like the second-generation Infiniti M45 stand out for their reliability and power. The average age of cars on the road today is about 12 years and continues to rise, partly due to increasing new car prices. Many owners of older cars prefer to hold onto them rather than navigate the complexities of modern automotive technology.
A Gem for Enthusiasts
For those who prefer older-school build quality with modern levels of power, the second-gen Infiniti M45 is an excellent choice. This vehicle can be purchased for less than $5,000, making it an attractive option for budget-conscious buyers. The Infiniti M45 boasts a 4.5-liter V8 engine, producing 340 horsepower, which was impressive for its time, outperforming some of its more expensive competitors like the 2003 Jaguar XJ8 and BMW 540i.

Reliability and Performance
Despite being an older luxury car, the Infiniti M45 is regarded as exceptionally reliable. Reports from owners indicate that some vehicles have exceeded 200,000 miles with only routine maintenance and a few medium-severity repairs. The car’s reliability, combined with its powerful V8 engine and rear-wheel drive drivetrain, makes it a compelling choice for those seeking a performance-oriented luxury vehicle.
The Infiniti M45 features a 4.5-liter Nissan VK45DE NA V8 engine, paired with a five-speed automatic transmission. Its performance specs include:
- Horsepower: 340 hp
- Torque: 333 lb-ft
- 0-60 MPH Time: 5.7 seconds
- Top Speed: 147 mph (limited)
Features and Pricing
The second-gen Infiniti M45 comes with a range of luxury features for its time, including automatic dual-zone climate control, an ambient outdoor temperature display, and a 225-watt Bose stereo system with seven speakers. The average used price for the 2003 and 2004 models is around $4,751, according to Kelley Blue Book.
Comparison with Other Models
While the third-generation Infiniti M, introduced in 2005, received positive reviews for its styling and features, the second-gen M45 remains a great buy for those who appreciate its unconventional styling and higher power output. You can purchase a 2006 Infiniti M45 for around $5,840, but it has five fewer horsepower than the second-gen model.
In conclusion, the second-generation Infiniti M45 offers a unique blend of power, reliability, and luxury features at an affordable price. Its unconventional styling and impressive performance make it a standout choice for enthusiasts looking for a used luxury car.
