This is an odd question, I am sure, but we bought a used Mini Cooper, but it didn't come with an owner's manual. We have figured out how to open it with the key fob, obviously.
The problem comes when we want to pop the trunk and quickly pull something out when the car is running. This Mini doesn't have the keyless start option. So we actually have to turn off the engine to get the key out to pop the trunk.
This seems ridiculous to me, since all the other cars I have driven have a latch somewhere inside the car to pop the trunk.
