thinking of buying e class 2003-2007 but how reliaible are they anyone???
1) 2007-2009 is the refresh so there are likely to be some improvements
2) Air suspension can be problematic and will be expensive to fix
As for miles, who knows...
Our '05 cdi has been damn near bulletproof for over 100k miles, with the only unscheduled repairs to date being 2 SRS airbag sensors, 1 EGR, and one keyless-go door handle. I'll let you know how it's holding up when we get to 200k...
It will now go back to the shop because of the infamous no dipstick and a malfunction telling me I have too much oil. Interesting since I drove it 3 months after service with OK showing. Guess it is making oil and perhaps I should take some out and sell it at $71/bbl.
