Insurance & Registration

  • E46 330s are relatively affordable to insure due to age and value
  • Full coverage may not be cost-effective on lower-value examples
  • Agreed-value or classic car policies available for well-maintained examples
  • Track day coverage typically requires separate policy or rider
  • Modifications can affect insurance — disclose major changes
  • Standard registration in most states
  • Emissions requirements vary by state:
    • California: SMOG check required, modifications can cause failure
    • Most states: OBD-II emissions test (no codes = pass)
    • Some states: No emissions testing
  • Classic/antique plates available in some states for cars 25+ years old (2024+)
  • Intake/exhaust modifications generally don’t affect insurance
  • Forced induction (turbo/supercharger) should be disclosed
  • Suspension modifications generally not a concern
  • Major engine swaps may require engineering certification in some jurisdictions
