I rented a Ford, which is a locally-made British car. It doesn't have a reverse radar! Additionally, the rental price for this car is lower than what I paid, essentially giving me a downgraded vehicle. The car constantly showed warnings, such as oil lamp, maintenance alert, and low battery! We were right in the middle of the highlands near Edinburgh, far from any villages or service areas, and I was extremely worried during the drive, which affected the trip. I reluctantly drove it to Edinburgh, and the warning lights disappeared. During the car return, the rental company inspected it and claimed everything was normal.
