It's insurance renewal time for the CLS55 .. Quotes have ranged from £2600 (Mercedes Insurance) to £922 .. It's down to Chaucer (£922, £300 excess) and Market Study (£929, £500 excess). Any one has any experience of either Chaucer or Market Study? Am leaning toward Chaucer as it's the lower excess. For comparison, Admiral wanted £1250 (was £825 when I was insured with them last year). Admiral again did their trick of quoting a much higher premium for renewal when compared to new business. They have lost my business this year.
