Insurers

[Germs]

Any suggestions re insurance companies for a 55 year old with a clean licence but 2 crashes in the last 3 years (hitting a column in a Waitrose carpark and scraping the paint off another car's bumper with a trailer)? Looking to insure an '11 plate 350SLK, tried my current insurer (not interested) and another who advertises on the MB sites. Any suggestions greatfully received. Thanks in advance.
