1998 Mercedes-Benz E430 Reviews

i own 2 of these cars,one of the best models that mercedes has build. small problems here and there,nothing major. get the car repaired by the best independent shop in town and have no issues.250k miles and no car payments goes a long way.
Car run smooth & accelerates good. Have had check engine light go on several times and was told the (2) rear oxygen sensors need to be replaced for $700 each. I did not have them replaced. Instead I used Z Max gas & oil additive and the check engine light went away. My son in law who took automotive tech said they had tested it in school and it works as claimed.
Great car; however, excessive repairs are needed, which is really costly.
