BMW E86 Z4 Coupe

The E86 Z4 Coupe, sold from 2006 to 2008, is the fixed-roof version of the second-generation Z4 roadster. Penned under Chris Bangle's design leadership, its 'flame surfaced' styling was controversial when new but has aged into a distinctive and muscular look. The coupe's chassis is more than twice as rigid as the roadster's, creating a focused driver's car. It was offered in two forms: the 3.0si with the 255 hp N52 inline-6 and the Z4 M Coupe with the E46 M3's legendary 333 hp S54 engine.

Collectors prize the E86 for its rarity, focused driving dynamics, and its fantastic naturally aspirated engines. The Z4 M Coupe, in particular, is highly sought after as it represents the last M car powered by the motorsport-derived S54. With a production run of only 2 years and relatively low numbers built, especially the M, the coupe is much harder to find than its roadster counterpart. It's a high-water mark for analog BMW performance before the brand shifted to turbocharging and more complex electronics.

With an average sale price around $20,000, the E86 Z4 Coupe remains an accessible modern classic. The market has a wide spread, with higher-mileage 3.0si models at the low end and pristine, low-mile Z4 M Coupes commanding prices near $40,000. Values have been steady, showing a gradual increase as more enthusiasts discover its unique combination of performance, style, and rarity.

Based on 59 recent sales, prices range from $8,000 for driver-quality examples to $39,000 for excellent, low-mileage M Coupes.
