Long-wheelbase TJ proportions, the legendary 4.0L inline-six, and a 6-speed manual transmission make this 2005 Jeep Wrangler Unlimited an increasingly desirable configuration from the final years of the TJ generation. Offered by a private seller in Frederick, Colorado for $18,000, this Flame Red example shows approximately 154,000 miles and spent roughly its first 20 years with one owner. It has reportedly been garage kept and spared from extreme off-road use, with a remarkably clean interior and an extensive documented maintenance history.
- Long-Wheelbase Unlimited: Introduced late in the TJ's production run, the Wrangler Unlimited stretched the standard TJ wheelbase to 103.4 inches and added meaningful passenger and cargo room while retaining the two-door body, solid axles, and traditional Wrangler proportions. Jeep's 2005 specifications list 29.5 cubic feet of cargo capacity behind the rear seat and 64 cubic feet with it removed, giving the Unlimited considerably more versatility than a standard TJ.
- 4.0L Inline-Six & 6-Speed Manual: This Wrangler pairs Jeep's 4.0L Power Tech inline-six with the NSG370 6-speed manual transmission, a particularly appealing combination for enthusiasts looking for a late-production TJ. The factory literature rated the 4.0L at 190 horsepower and 235 lb.-ft. of torque, with Jeep emphasizing its strong low-rpm torque delivery for four-wheel-drive use. The original build sheet confirms both the 4.0L engine and 6-speed manual transmission.
- 20 Years with Its First Owner: CARFAX shows the first owner purchasing the Jeep in 2005 and retaining it for approximately 20 years, initially in Florida and later Colorado. A second owner was reported in June 2025. The seller describes the Jeep as garage kept and not subjected to extreme four-wheeling.
- Extensive Service History: Few 20-year-old Wranglers come with this much documented maintenance. CARFAX records 49 service-history entries, including regular oil changes and inspections along with replacement or service of the water pump, transfer case, differential seals, rear brakes, oil pan, and other components over the years. Most recently, a November 2025 dealer visit included an inspection, fluid check, oil and filter change, tire inspection, and rotation.
- Mostly Stock, Well-Preserved Presentation: Rather than being extensively modified for trail use, this Unlimited retains a largely factory-style configuration. The original equipment includes a heavy-duty Dana 44 rear axle with Trac-Lok limited-slip differential, Dana 30 front axle, 3.73 gearing, Command-Trac part-time four-wheel drive, skid plates, and front and rear tow hooks. Exterior wear is limited to a small hood dent and some paint chipping across the front and one door according to the seller, while the interior is described as exceptionally clean.
- Three Top Configurations: The Jeep includes a Rally hardtop, its original black folding soft top, and an additional bikini-style top. The rear-window zipper on the original soft top is currently stuck. The factory build sheet confirms that this Wrangler originally left the factory with the black folding soft top.
About the 2005 Jeep Wrangler Unlimited
The 2004 introduction of the Wrangler Unlimited created something Jeep had never previously offered in the TJ generation: a substantially longer-wheelbase Wrangler that retained the classic two-door layout. Its 103.4-inch wheelbase was roughly 10 inches longer than the standard Wrangler, providing additional rear-seat and cargo space while preserving the solid-axle, body-on-frame formula.
For 2005, the formula became particularly interesting with the arrival of the NSG370 6-speed manual transmission. Combined here with the 4.0L Power Tech inline-six, 3.73 gearing, Dana 44 rear axle, and Command-Trac four-wheel drive, it gives this Unlimited a drivetrain configuration closely associated with the final evolution of the traditional TJ.
This example's history is equally compelling. Its first owner kept the Jeep for approximately two decades while accumulating the majority of its mileage, and the CARFAX history contains 49 service records rather than long periods with no documented maintenance. CARFAX does report an accident in June 2014, but reports no total loss, structural-damage brand, airbag deployment, or odometer discrepancy.
For someone looking for a TJ-era Unlimited to actually drive, the appeal is straightforward: 4.0L power, three pedals, the longer Unlimited chassis, useful factory 4×4 hardware, limited modifications, and a long maintenance paper trail.
