We recently returned from a trip to Ireland. After four days in Dublin we returned to the airport to pick up a car we had reserved from Sixt to drive for 5 days across Ireland and return to Shannon Airport. We were surprised to learn that because I am 76 years old (and I didn't read all the fine print) that I could be denied that rental. According to the agent, I should have brought a letter from my physician attesting to my fitness to drive after 75. I was told that this is an insurance requirement throughout the EU. In filling out the on-line document for the rental, I was never asked my age. I managed to covince the agent and the manager to waive the "fittness document" and we proceeded to rent without complication.
I hope you will publicize this requirement so other, older travelers will be prepared when traveling abroad. I would also encourage the car rental companies to include questions about birthdate on their on-line applications to prompt notices that a "fitness letter" will be required.
Sincerely,
Michael Grunko, Somerville, MA
