This is for driving lessons not pass plus! The pic in the op's description is a little misleading.
Portsmouth here too and another deal daughter will like. Thankyou
I did pass plus when I first passed my test (about 10 years ago though) and it reduced my insurance quotes from about £2000 to £1000. Even if it doesn't give you such a huge discount it is worth doing just for the night-time and motorway driving experience alone. I can't believe that we still let people pass a driving test in the UK despite not having any experience driving in the most dangerous conditions.
HOT I'd say... you'd probably get more than £45 knocked off your 1st insurance for doing this so I'd say it was well worth it.
They also drive to you and it doesnt come out of your hour, Ive already booked up my lessons =]
