...a sunroof is a blessing...if you are tired of hearing the birds you can concentrate on your engine noise......best sound ever..
.
I drive nearly whole year through with an open roof so the risk of leaving it open increases.... 
My wife left it open on the MK V say 3 times when shortly afterwards it started raining....you will not believe how your car looks like the next morning....so an automatic roof-closing is nearly a must...
.
BTW...in the end I was glad that she left it open....it gave me no discussions when I ordered leather....
......
(1) Get too much bird sh!t in London. True.
(2) Sh!tty weather in London. It is always raining. True.
(3) Our birds don't sing anymore. So true.
(4) Both you and your dear wife are into leather. Admit it! Fact.
(5) I could not afford a sunroof. Lies.
(6) O hell! I wish I had ordered one + mud flaps (flippers). Lies.
3 Trues. 2 Lies. 1 fact.
Hence did not order sunroof. I can be logical!
BTW: Saw a Golf with the flippers. A white one. Looked just like what our birds do!
