The Tesla Model S 100D (2018) with AP2.5 (Autopilot 2.5 Hardware) offers a compelling mix of performance, range, and advanced technology. Here’s a breakdown of its key benefits:


1. Long Range & Efficiency

  • 100D Battery: Delivers ~335 miles EPA-rated range (when new), making it ideal for long-distance travel.

  • Dual Motor AWD: Provides excellent traction, efficiency, and smooth acceleration (0-60 mph in ~4.1 seconds).

  • Lower Energy Costs: Compared to gas-powered luxury sedans, charging is significantly cheaper.

2. Autopilot 2.5 Hardware (AP2.5)

  • Enhanced Autopilot (EAP) or FSD Capable: Depending on software unlock, includes features like:

    • Traffic-Aware Cruise Control

    • Autosteer (lane-keeping)

    • Auto Lane Changes

    • Summon (basic Smart Summon if FSD is enabled)

  • Future-Proof for FSD: AP2.5 is hardware-ready for Full Self-Driving (FSD) upgrades (though FSD purchase/activation may be required separately).

3. Warranty Coverage (Likely Remaining)

  • Basic Vehicle Warranty: 4 years/50,000 miles (from delivery), possibly still active if purchased late 2018.

  • Battery & Drive Unit Warranty: 8 years/unlimited miles (for 100D), ensuring long-term reliability.

4. Premium Comfort & Tech Features

  • Spacious Luxury Interior: Premium seating (optional ventilated/heated seats), minimalist dashboard with large touchscreen.

  • Glass Roof: Expansive panoramic sunroof for an open feel.

  • Premium Audio: Tesla’s upgraded sound system available.

  • HEPA Bioweapon Defense Mode (if equipped): Advanced air filtration.

5. Software & Connectivity

  • Free Over-the-Air Updates: Regular Tesla software improvements for performance, safety, and infotainment.

  • Tesla App Integration: Remote climate control, charging management, and security features.

6. Strong Resale Value

  • Tesla’s brand cachet and battery warranty help maintain value better than many luxury sedans.

  • AP2.5 hardware is desirable for buyers looking for Autopilot capabilities.


Potential Considerations

  • No Free Supercharging (unless transferred): Most 2018 Model S cars no longer include free unlimited Supercharging (unless it was a rare „referral“ car).

  • FSD Status: Verify if Full Self-Driving was purchased (or if only Enhanced Autopilot is included).

  • Battery Health: Expect ~10% degradation after 5+ years (~300 miles max range now).


Verdict:

The 2018 Model S 100D with AP2.5 is an excellent choice for buyers seeking:
✅ Long-range capability (great for road trips)
✅ Advanced Autopilot features (with FSD potential)
✅ Luxury EV comfort & tech
✅ Strong warranty coverage
