Today I was planning on renewing my Tier 1 warranty with Mercedes. I bought my 2004 E55 AMG 1 year ago and paid £1100 for a Tier 1 warranty with £0 excess. I was also told that a renewal price if it wasn't a lapsed policy was £800. Shocked at my renewal price today - £1550 (mileage on the car is less than 60,000miles). Effectively 100% increase on what I was expecting (OK I was expecting maybe a 10% increase on the £800) No comment or movement on the price from MB warranty - the price is the price apparently.
