Each part is scored from 0 to 100 on a fixed outside scale. Acclaim comes from published expert lists, launch reviews and awards; the more acclaimed a car, the less its ownership cost counts in this all-time score (its dollars below are unchanged). A part marked not measured carries no weight for this car, and the others share its weight.

Long-term value, shown and not scored

3 prices from sources that allow this use (driveway.com), read October 27, 2026: the middle one is $36,999, about 49% of the price new (35% once the price new is put in today's dollars). Asking prices sit above what cars sell for.

Long-term value starts to count in the score once 75% of the 69 generations have permitted prices. Today 43 do.

The cost to own

About $2,512 a year to own ($1,604 to $4,166), about $11,872 over five years, bought at five years old or its own age if older, kept five years.

  1. Crank hub slippage: about $360 over five years, rare (source)
  2. Rod bearing wear: about $215 over five years, rare (source)
  3. Retractable hardtop mechanism: about $180 over five years, possible (source)

Expect about $1,600 to $4,200 a year; the bills that decide it are crank hub slippage, rod bearing wear and retractable hardtop mechanism. Ownership risk: moderate.

Best year to buy

2020The best year to buy, reading 83 of 100, about $2,491 a year to own.

No logged change between model years sets it apart; every year reads within 2 points of it, so buy on condition and records.

No year to think twice about: none reads 3 or more points below the 2020, and no logged fault separates them.

From our log of the changes between model years, each with its source. Only changes the score reads count as reasons; recalls BMW fixes for free, options and tuning notes do not. The cost a year is for a car bought at five years old, or its own age if older, kept five years. How the score works.

The longer answer

Inherits the F82's character and chronic issues but is about 500 lb heavier, less rigid, and more cruiser focused, a different buyer than the coupe.

What to look for
  • All F82 checks (S55 crank hub, charge pipe, cooling, oil leaks, a leaking fuel tank) plus the retractable hardtop mechanism, hydraulic pump, trunk dividers, and any moisture damage
  • Verify the top cycles fully through every position
  • Ask whether BMW's drain fix has been done (SI B01 08 26, which replaced SI B51 33 16; a dealer confirms BMW's 15-year, 150,000-mile cover by VIN), look for water under the rear seat and in the trunk, and check recalls by VIN

Holds value

  • Working retractable hardtop
  • Competition Package
  • Six-speed manual
  • Signature colors
  • Low documented mileage
  • Complete records

Hurts resale

  • Top mechanism faults
  • Hydraulic pump issues
  • Water damage
  • Accident history
  • Undocumented heavy tuning
  • Common colors
