Z4 M vs Boxster S vs SLK 55

LOL! Jim, you are taking it too personally. Richard is suggesting a possible cause of early failure, not saying you or your dad actually are negligent in that respect.

I understand your point, but he suggested a cause that would be negligent maintenence without knowing any specifics about the car. Now that he knows the car got oil/filter changes at half the factory recommended intervals, he's still pushing the "didn't change the oil enough or something" BS.

Yeah, half the factory recommended interval isn't near enough. Of course you knew that before you wrote this latest piece of BS............

That's ok, do better next time. Try half the factory recommendation.

Why? Do you do the same with all the fluids in the car, and if so why not?

Jesus. I hear there's a sesne of humour on ebay. They take paypal and ship internationally.

Both the SLK and the Z4 are hairdressers cars.

Whatever you say, Dick.

That's the spirit. Hope this helps.

Not really, dick.

I think you need to capitalize that.
