Overall, it was a smooth experience. They tried to upsell a higher model and insurance, but after learning that I already had full insurance from QEEQ and experience with renting cars abroad, they didn't insist. It's understandable as it's part of their sales process and shouldn't be taken too seriously. We didn't get the Grandland but were given an equivalent MG ZS with over 10,000 kilometers. The 1.5 engine felt a bit underpowered, but it was manageable with the manual transmission and generally sufficient for the speed limits in the UK. Overtaking was a bit challenging, but both cars are probably of similar quality. No extra charges for returning the car so far. To ensure peace of mind, take photos and videos of the car inside and out before picking up and returning it, keep the gas receipts, and you should be fine.

There were many counters when I arrived to get a ticket and wait in line.

There is a free shuttle bus from the airport, but the pick-up point at London Heathrow Airport was hard to find, and we had to wait a long time for the Europcar shuttle. The rental office is quite far from the airport. The car pickup was smooth overall; we booked an Audi A4 but received a Mercedes C-Class. The staff didn't try to upsell anything, but they also didn't provide detailed information on driving rules and other considerations.

The drop off location at Gatwick north terminal is not very well signposted and the turning easily missed.

They got my booking mixed up with someone with the same last name. Utter morons
