I got my insurance through the C.I.S. as i used the car for work and have to do 1000 miles a month to see my bambino my cover is now for 40,000 miles and as a 25 year old some of my quotes were out of this world, the lexus club insurance qouted me £1300 at c.i.s. it is £700. worth a call.
off the top of my head the number is 08457 464646 i think thats right. I told them i was changing to a set of 18" alloys which would add value to the car and all they said was send us a photo so we can update our records. no extra on the premium.(not getting the wheels now though , dodgy boiler, long story). The only problem with c.i.s is you might have to sit down with a financial adviser but i just refused to talk about anything else to him.
cheers
