Booked my car through the sixth app. All good so far but the best part was at the branch. The guy at the counter, Shahid, helped me through the DVLA check and also offered me an upgrade of the car for free. I was very pleased, the car was amazing, the journey went perfectly and the return procedure was super easy. It's not my first time with Sixth and won't definitely be the last! Thank you guys, thank you Shahid! Great customer service! See you soon
