To be honest, I would have thought your insurance would be less on a Golf GTi.
My last car was a Mk5 Xr3i 1.8 105bhp with non-standard Alloys. Im 25 with 4yrs no claims this year and throught my insurance would almost certainly go up on the Golf. As it turned out, they only charged me the £10 admin fee to change as I only have a month to run.
I went on my insurers (Elephant) website to get some quote ideas for next year, and it was actually quoting me about £100 cheaper then they had been on the Xr, and I was even given a cheaper quote to go fully comp which was amazing. I've been with Elephant for the last 2yrs, and I can see me sticking with them again so it would probably be worth you giving them a try. I always shop around, but last year no one came even close to them, some companies even quoted double and insisted on a cat 1 on the Xr. naff.
I dont think you'll have too many problems if you've already been getting insurance on the Rover.
Let us know how you get on.
