Just insured my BMW through Sky finding me a really good deal.
I spoke to a bloke called Sam and he really couldn't do enough, refreshing change.
With a mention of Club G40 you also get a 20% discount so I thought I would mention it on here.
Depending what cover you go for, they are also modification friendly.
Have been insured with them on both cars for 3 years in a row now. Usually highly competitive on anything modified. Had a bit of a haggle this year as I found other insurers 5-10% cheaper on each of my other cars come renewal time, but they matched it with a higher level of cover.
Big bonus for me is you get to speak to a human being pretty quickly and time on hold is minimal/non-existant.
Only issue I've had is some mong woman getting confused about my NCB this year, but her manager rang me back as promised and sorted it within minutes.
