Overall good, but I have a small complaint. When we arrived at the pickup point, they spent quite a bit of time trying to upsell us different upgraded models. I wouldn't mind this normally, but they ended up using nearly 30 minutes for the sales pitch and counted that as part of my rental time. This means the rental period started from the moment they greeted me, not when we finished the process, and 80% of that time was spent on upselling.

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.

They should inform us in advance about local traffic violations and parking regulations.

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.

Like: Pleasantly surprised by how helpful the Europcar office staff were with limited upsell.
Dislike: I got slightly confused at Heathrow T2 over which bus stop to use for the shuttle - some better signage that can be seen at a distance would help.
