Good

Picking up and dropping off the car at Heathrow Airport T4 branch is very convenient.

Used to recommending vehicle upgrades. The cross-border and cross-island fee of £309 is inconsistent with the original statement of £187, nearly doubling the cost.

The rental location is near the airport, with a dedicated reception desk at the airport exit directing you to a shuttle bus for car pickup. The pickup location is spacious with many service staff who are very friendly. The paperwork is correct, and someone accompanies you to pick up the car and explains the usage precautions. The process is smooth and fast.

Terrible experience with Europcar. Bad communication on return location and issue with faulty car which has still not been resolved. After returingn the car to the correct location I was sent threatening letters over a 48hr period because they had not checked the location and were accusing me of not returning the car.

Like: Well priced for size of car, well known rental company, quite a simple process overall.
Dislike: Car booked was a Skoda Superb or similar, which is quite a large car. Car issued was a Skoda Octavia, which is the next size down.
