Strengths

  • B58 inline-6 in M40i is brilliant
  • 2024+ manual is a real gear-lever return
  • Same platform as Supra A90

Weaknesses

  • Soft-top is heavier than F30 metal-roof
  • Toyota-shared platform divides purists
  • Pricing pushes past Boxster S

Notable tech

  • G29 platform jointly developed with Toyota Supra
  • RWD only
  • 8-speed automatic standard
  • 6-speed manual added 2024+ for M40i (US-only)
  • Adaptive M suspension on M40i
  • Soft-top only (no folding hardtop)

Common issues

  • B58 valve cover seal seepage
  • Soft-top motor wear
  • Some Toyota-shared infotainment quirks

Used-market budget

$48,000

Typical price point for a well-maintained example with full service history. Cars priced significantly below this often require remedial work.
