ML's are fun to drive, but the reliability is not there. If you are truely looking for reliability, do your honest research and review the various available industry reports over the last 9 years on ML's.
I had two ML's, a 2001 and currently a 2005, both with terrible repair records that have cost me several thousands of dollars in repairs.. $10,000+. I am the last among my friends to still own one of this ML's and I am sure paying the price on the lack of reliability. Browse all the Mercedes forums and review the various available industry reliabilty reports/surveys from various companies..
Mercedes repairs can easily cost you a couple of thousand dollars for each repair, and there is no guarantee that the problem is really fixed or that can be fixed because of the poor design and bad quality of the parts. i.e. Power steering pumps, power steering racks, CPS, transmission solenoids, gear and transmission controller problems, AAMS, ECU, trip computers (control towing sensors, etc), sensors, iginition coils, bad failing keys ($3000.00 after your keys fail 8 times so before buying an Ml check how many keys are left before you have to pay $3000.00+), etc. Not to add bad Mercedes repair dealers, expensive parts, etc...
Never buy an ML without a warranty or extended warranty that will cover the number of years and mileage you plan to own it.. Old Mercedes vehicles, early 1990's and before, were good solid vehicles.. Post 1995's, or so, Mercedes are really a sad story on overall reliability...
