Hi There
One of the most surprising places to try for insurance is.......BMW!!!
I insure my 1997 E36 328 touring with them for Ԛ£492 fully comp. That includes me and my wife to drive, I have an SP30 and my wife a DR10

yep!! from a couple of years ago!!
Just make sure you use their online quote system, cause the prices vary drastically by phone them...(eg Ԛ£790 phone call, Ԛ£492 internet with all the same details)
I have 9 years plus NCB unprotected.
I have my 1989 325i sport insured with (will post later, cant remember their name

) and I pay again Ԛ£492 with no NCB
Both cars are off road parking and in the Glasgow area.
Hope this helps.
Cheers
