"Please" If its this enjoyable, should you need to say that?
120 mins - Are we enjoying this because its 120 mins? IMO "2 Hours" sounds better, although I doubt whether anyone was ever in a seriously bad mood until they parked (unless they really really don't like looking for a car park).
Red? I realize you have to stop the car for it to qualify as parked, but the red seems quite aggressive.
Fine print - "Take Care" - really? Do you mean: Don't ram my car into this space? Or generally? In red again? Net result: No.
