There isn't a single "best" car for a tour guide in Iceland, as the ideal vehicle depends on various factors such as group size, preferred activities, and budget. However, here are a few options to consider:

1. 4x4 SUVs: SUVs like the Toyota Land Cruiser, Land Rover Defender, or Jeep Grand Cherokee are excellent choices for navigating Iceland's diverse terrain. Their high clearance, four-wheel-drive capabilities, and spacious interiors make them suitable for both on and off-road adventures.
2. All-Wheel Drive (AWD) Crossovers: AWD crossovers like the Subaru Forester or Nissan X-Trail offer a balance of comfort and off-road capabilities. They may not be as rugged as 4x4 SUVs, but they can handle most Icelandic roads and provide sufficient space for passengers and luggage.
3. Minibuses or Vans: For larger groups, minibuses or vans such as the Mercedes-Benz Sprinter, Ford Transit, or Volkswagen Crafter are ideal. They can accommodate more passengers and provide ample space for luggage and equipment.
4. Camper Vans: If you plan on offering multi-day tours that include camping, consider a camper van like the Volkswagen California or Ford Transit Custom. These vehicles offer sleeping and cooking facilities, allowing your clients to experience Iceland's natural beauty up close.
5. Electric Vehicles (EVs): As Iceland continues to promote sustainable tourism, opting for an electric vehicle like the Tesla Model X or Y could be an eco-friendly choice. However, keep in mind that charging infrastructure may be limited in remote areas.

Regardless of the vehicle you choose, make sure it is well-maintained and equipped with appropriate tires for the season, as well as emergency and safety equipment. Check local regulations and requirements for tour operators and ensure your vehicle meets those standards.If you are still unsure, simply contact my with your thoughts and I will tell you my thoughts on the matter.
