Long-wheelbase TJ proportions, the legendary 4.0L inline-six, a 6-speed manual, and single-owner history from new 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 $15,000, this Flame Red example shows approximately 154,000 miles and has remained with the same owner since 2005. It has been garage kept, spared from extreme off-road use, and supported by a complete service file dating back to purchase. A 2.5-inch lift and Rally hardtop were added in 2021, while the rest of the Jeep remains largely true to the simple, mechanical character that makes the long-wheelbase Unlimited so appealing.
- 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 strong low-rpm torque well suited to four-wheel-drive use.
- One Owner Since New: The seller purchased the Jeep new in 2005 and has remained its only owner. A 2025 title update that appears as a second ownership event on CARFAX was simply a legal name change following marriage, not a transfer of the vehicle. The Jeep has been garage kept throughout ownership and was used primarily on-road, with no extreme four-wheeling.
- Complete Service History: Every service record since purchase has been retained, giving the next owner an unusually complete maintenance paper trail for a 20-year-old Wrangler. Documented work includes regular oil changes and inspections along with service to the water pump, transfer case, differential seals, rear brakes, oil pan, and other wear items over the years.
- Lightly Modified, Well-Preserved Configuration: A 2.5-inch lift was installed in October 2021 when the Rally hardtop was added, giving the Unlimited a little more stance without turning it into a heavily modified trail build. Factory hardware 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.
- Three Top Configurations & Extras: The Jeep includes a Rally hardtop, original black folding soft top, and bikini-style top. The Rally hardtop has been garage kept since installation and remains in very good condition aside from a couple of light surface scratches on the driver side. The original soft top has not been installed since 2021 and has a stuck rear-window zipper. Also included are two keys, the owner's manual, complete service records, mirrors and light clips for use with the bikini top, and a new-in-box overhead garage storage hoist.
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 adds something increasingly difficult to find: true single-owner history backed by a complete maintenance file. The Jeep has remained with the same owner since new, accumulated its mileage gradually over two decades, and avoided the heavy modification and hard trail use that define many surviving TJs.
For someone looking for a TJ-era Unlimited to actually enjoy, the appeal is straightforward: 4.0L power, three pedals, the longer Unlimited chassis, useful factory 4x4 hardware, a mild 2.5-inch lift, multiple top configurations, and unusually complete ownership documentation.
