What should I look for in a used Mercedes E-Class estate?
The previous generation of E-Class ('02-'06) didn't do any favours to Mercedes' reputation for reliability. Thankfully, this newer model restored some of the good faith, but it's not perfect.
The automatic gearbox can be temperamental and, in the worst cases, owners could face a substantial replacement fee, while the largest diesel engine can suffer terminal issues with the injectors. There's also a possible problem with the camshaft position sensor, which could cause the car not to start.
