Recalls & safety

Pros & cons

Pros

Capable all-wheel-drive system and a solid, well-built body.
Engaging, naturally-aspirated driving feel and sharp handling for an SUV of its era.
Affordable entry into a genuine luxury SUV, with the durable M54 inline-six (3.0i) as the smart pick.

Cons

N62 V8 oil leaks, valve-stem seals and transfer-case repairs are expensive.
Thirsty V8, dated interior and technology, and high parts and labor costs.
Aging plastic cooling components fail with age and must be proactively replaced.

Depreciation

2006 entry trim from new typical floor (assumed, past curve data)

Move your cursor along the line to see the estimated value for any year.

Curve anchored at the entry-trim base MSRP ($43,195). Higher trims started higher (up to $71,795), and options added more.

The curve's data ends 10 years in, so the line levels off after that. Treat the tail as a floor, not a forecast: asking prices for older cars depend mostly on condition, mileage, and the current market, and often sit well above it.
