  • EU-Rent operates in several countries; in each country it has local areas containing branches
  • EU-Rent rents cars to customers from branches; one-way rentals are allowed
  • Rentals may be booked in advance or ”walk-in”
  • Cars are owned by local areas and stored at branches
  • Each car is of a given model;car models are grouped into car groups; all cars in a car group have the same rental tariff
  • Cars are serviced at 5.000 miles intervals
  • EU-Rent notes ”bad experiences” with drivers (police action, unpaid parking fines, cars damaged or not returned to EU-Rent branches, etc.) and may bar drivers who cause them.
