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.
