Really should have been made aware of the importance of preregistering our car with TFL and been made aware of Congestion Charge Zone.

Good service, they offered insurance but didn't push when I declined.

The store forced me to buy full insurance when picking up the car. The vehicle was not sanitized and there was trash inside. The interior was very dirty.

Picking-up a car took almost 2 hours; the car is not really at terminal, they took me about 10 miles away from the airport to the car; dropping off is also terrible - there is no signs on the place, I winded around few times until found them; the car was vandalized, though that was not my fault, and I reported police, they charged me 1500GBP (abt 2000US$) for 4 small scratches! Never rent a car with SurPrice car rentals!!!

Waited for ages for office to open as dropping off another customer. Found the office hard to find from the instructions. Hated the shuttle bus system - I think I overreacted; others might find it fine. Friendly and helpful staff.
