Just had my renewal from LV, 20% increase compared to your 40%. I'll shop around but I do like LV as an insurer, I've had a good experience with them both as a claimant and third party.
A slightly left field suggestion, but have you tried VW insurance for a quote.I wouldn't have even considered getting a quote from a manufacturers broker, but last year when I got my new SQ5 and needed comprehensive insurance for myself, wife and 26 year old daughter including business use, I tried Audi Insurance as the quotes I was getting from the comparison sites were in the £1200 to £1400 price range and all needed a tracker fitting (another £500 or thereabouts).As I had signed up for the 5 day cover through Audi I thought I would get a quote out of curiosity and they came in at £870. This years renewal dropped to £740, so I didn't even bother searching around.
Does that include the modifications?
Just to update this thread i have now gone with Sheila's' Wheels believe it or not, mainly because they were with best price with modifications declared but also because they got better reviews as a company. Saw a lot of bad reviews for VW insurance which put me off. Still managed to save over 200 quid from the LV quote so I'm happy with that.
