Not a great car.

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.

Waited nearly an hour at Heathrow Airport due to the crowd; I got a manual car which I don't think matches the model I paid for.

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.

Europcar forced a downgrade. I returned on the 1st, and it's now the 19th with still no resolution. When I discovered an issue at pickup, they treated us differently, saying you rented through a third party, and we didn't receive your payment, so Europcar can't handle it.

I took my rental car from Heathrow. At Manchester airport, the car had a flat tyre. I managed to drive to Europcar at Manchester Airport to get it repaired. But they decided to provide me with another car. Same model Toyota Corolla Hybrid. The guy who attended to me was MAURICE. Grateful to him for his prompt action and very fast to provide with another car. At the end of the journey I have to thank the front desk at Heathrow airport for convincing me to take the Hybrid Toyota. I ended up driving almost 1100 miles and it really save the fuel. Europcar was also flexible for me to drop the car in London instead of Heathrow. (drop box was available) this is my second time renting from Europcar.

I swap with another car so no comment on that matter.
