Every unit includes leather seating, panoramic sunroof (where available), adaptive cruise control, wireless phone charging, and a premium audio system. German models add air suspension and a head‑up display.

Is the premium SUV worth the extra cost?
If you value lower fatigue on long drives, latest safety tech, and a refined cabin, the upgrade pays for itself in comfort. For short urban hops, a standard SUV may suffice.
Can I rent a premium SUV for a cross‑country road trip?
Absolutely. Unlimited mileage plans, spacious cargo areas, and advanced driver aids make these vehicles ideal for multi‑state journeys.
What fuel should I use?
Premium unleaded (91 octane+) for BMW, Mercedes, Audi, and Porsche models. The Toyota RAV4 Hybrid runs on regular unleaded. Always verify the fuel‑type sticker inside the fuel door.
Are there age or license restrictions?
Renters must be 25 + (21‑24 with a surcharge) and hold a valid, non‑probationary driver’s license. International renters need an International Driving Permit if the license isn’t in English.
