📚 Vehicle History

Jeep Legacy:

Founded in 1941, Jeep is synonymous with off-road capability, military vehicles (Willys MB), and rugged SUVs. Its vehicles are known for durability and go-anywhere attitude.

Generation:

First generation (2002-2007). Introduced as a successor to the Cherokee (XJ) in North America, but maintained 'Cherokee' badging in most international markets. Known for its unibody construction and more car-like ride than previous Jeeps.

Generation:

Third generation (2005-2010). Marked a significant redesign with a longer wheelbase, independent front suspension, and a more sophisticated interior and technology suite. Offered a wider range of powertrains, including the HEMI V8.

Generation:

Second generation (1997-2006). Continued the iconic Jeep design with round headlights, a leaf-spring rear suspension for off-road articulation, and a removable top. The 2005 model year was part of the later stages of the TJ's lifecycle, benefiting from refinements.

Manufacturing Locations:

Jeep vehicles are primarily manufactured in North America, with key plants in Toledo, Ohio (Wrangler, Liberty), and Detroit, Michigan (Grand Cherokee).

🏆 Awards & Recognition
