Okay Gareth,
I've just done what you suggested and went back to the same online insurance company and entered details of the 911 (it was a 2005 plate) I sold last week.
The quote came back 72% higher than last year! So you were indeed correct - its the premiums that have sky rocketed this year!
So in fact my change to the A4 has saved me lot of money on insurance!
Many thanks for your sage advice 🙂
Cheers,
Colin
