Pick the car like an expat, not a tourist.
- Book an automatic. The surcharge is the best money you'll spend on the trip.
- Go mid-size. Wider cars suffer on hedgerow roads. Save the upgrade for a hotel.
- Confirm insurance coverage in writing before you leave the US. Most cards exclude Ireland.
- Pick up the car the day you leave Dublin. Not the day you arrive. Not at all if you're staying in the city.
