Act as an expert UK Vehicle Import Consultant specializing in DVLA regulations, HMRC requirements, and Individual Vehicle Approval (IVA) processes.

CONTEXT:
- Vehicle to import: [VEHICLE_SPECS] (e.g., 2019 Tesla Model 3, 1995 Toyota Supra RZ, Ford F-150)
- Country of origin: [ORIGIN_COUNTRY] (e.g., USA, Japan, Germany, UAE, Australia)
- Vehicle age: [VEHICLE_AGE] (years old at time of import)
- Import purpose: [IMPORT_SCENARIO] (e.g., moving residence permanently, classic car investment, purchased from abroad, temporary import)
- Current compliance status: [COMPLIANCE_STATUS] (e.g., EU type-approved, unknown/needs assessment, already modified for UK)
- Target timeline: [TIMELINE] (e.g., urgent/within 2 weeks, standard/2-3 months, flexible)

TASK:
Provide a comprehensive, legally accurate, and actionable guide for importing and registering this vehicle in the UK. Structure your response as follows:

1. **IMPORT PATHWAY DETERMINATION**
   - Identify applicable route: Mutual Recognition (EU/EEA vehicles), Type Approval exemption (10+ years old), Temporary Admission, or Full IVA
   - Specify exact DVLA forms: V55/4 (new/unregistered), V55/5 (used), or V267 (temporary)
   - NOVA (Notification of Vehicle Arrival) requirements and 14-day deadline

2. **TAXATION & DUTY ANALYSIS**
   - VAT calculations (20%) and duty rates (10% for non-EU, post-Brexit EU rules)
   - Personal vs commercial import implications
   - Relief eligibility (Transfer of Residence ToR1 for permanent moves)

3. **COMPLIANCE MODIFICATIONS CHECKLIST**
   - Lighting: Headlight beam pattern conversion (left-hand drive to UK RHD pattern), rear fog light positioning (offside/left)
   - Instruments: Speedometer primary display in mph (km/h secondary permitted)
   - Safety: Seat belt anchorage standards, emissions compliance (Euro standards for vehicles under 10 years)
   - Specific considerations for: electric vehicles, motorcycles, commercial vehicles

4. **IVA TESTING PROTOCOL**
   - Category determination: Basic IVA (low volume) vs Normal IVA (mass production)
   - Documentation package: Certificate of Conformity (CoC), Mutual Recognition Certificate, or individual build evidence
   - Test center locations, booking procedures, and preparation standards (vehicle cleanliness, no fluid leaks)
   - Fee structure: £199 (Basic) to £450+ (Normal) plus potential re-test fees

5. **REGISTRATION WORKFLOW**
   - Sequential steps: Arrival → NOVA notification → Modifications → IVA booking/testing → DVLA submission → V5C registration document receipt
   - Insurance solutions for driving to IVA test (VIN/chassis number coverage)
   - Registration timeline expectations (2-6 weeks post-IVA)

6. **COST BREAKDOWN**
   - Itemized estimate including: shipping/freight, import taxes, IVA fees, DVLA registration (£55), modification costs (£500-£3000+), specialist agent fees (if applicable)

7. **RISK MITIGATION & EDGE CASES**
   - Q-plate risks (radically altered vehicles, kit cars)
   - DVLA rejection common causes (insufficient modification evidence, missing NOVA)
   - Left-hand drive (LHD) registration limitations and insurance implications
   - Brexit-specific considerations for EU imports (GB sticker requirements, headlight alignment)

Format with clear hierarchical headings, actionable bullet points, and include specific DVLA/DVSA reference codes. Highlight critical deadlines in bold. Conclude with a printable checklist summary.
