I now have 168K on my car. Bought it with 86K on the clock. As with any used car, check the wear items like brakes, shocks, tires, etc. If the car needs those items right away you could end up spending more than you anticipated. Condition of the suspension is important as well, control arm bushings and rear suspension links wear out over time. You might try to search the board with "E300d" to find out more about these cars.

I consistently get 32mpg and 37mph on long highway trips. Good mileage + big fuel tank provides 600-700 mile range per tank which is great. Although I wish the car had a bit more power for acceleration, it runs well at 70-80mph and has good power at that speed/rpms.
