Recalls & safety
Recall history hasn't been loaded for this model year yet.
Whether a recall is still open on a specific car depends on its VIN. Check it free at NHTSA's VIN lookup (nhtsa.gov/recalls), or ask the seller for proof the repair was done.
Pros & cons
Pros
- Near 50/50 weight balance and sharp rear-drive handling that defined the class.
- Silky, free-revving N52 3.0L inline-six with strong, linear power delivery.
- Solid build quality and a strong safety structure.
Cons
- High BMW maintenance and repair costs; oil leaks (valve cover, oil filter housing) are common with age.
- Electric water pump and cooling components are a costly, recurring failure point.
- Complex electronics raise the risk and expense of electrical faults as the car ages.

Depreciation
Move your cursor along the line to see the estimated value for any year.
This listing sits above the typical depreciation curve. Common for heavily-optioned cars and for 2021-2023 model years (pandemic-era pricing); the curve is anchored at base MSRP, which excludes options.
Curve anchored at the entry-trim base MSRP ($31,595). Higher trims started higher (up to $40,295), 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.
