Am about to purchase an 06 CLS55 from a private party and based on what I read here, it may be wise to pursue an aftermarket warranty. The car currently has just under 40k miles and seems to be well cared for by the owner. I am hesitant to go to the local MB dealer finance department - they are sharks. Any advice on how to go about this? (I am based in California, San Francisco area.)

Thanks in advance for your help.

contact Bruce Mendel <brucem105@comcast.net> he will set you up

Broadcast an email to all mb dealers in your area stating you want the max term and mileage for a exclusionary policy and don't forget to include a wheel package.
Also get a quote from mercury insurance. I ended up going with fidelity from flecter jones mb in newport beach
