Hi Jennifer, and welcome to the Club.
The 2.2 engine is quite a good engine, and was also used in the X Type and is powerful enough unless you want to race it.
Parking? You will have parking sensors to assist, and remember any Lady from Lancashire can park a tank! My wife used to love driving my Rover Sterling 825 which is just as long.
You will enjoy the Jaguar experience.
Regards,
Peter.
