Hello guys, it's been awhile since my last post here over a year ago...
Being sick and tired of having incompetent mechanics work on my beloved 240D (last time I was there for a full service fluid change/check, these guys - at EZ Lube in Los Angeles - didn't know which drain bolts were which, almost ruined the engine oil filter cover nut and inflated my rear right tire to a dangerously high pressure - I was lucky it didn't blow up on the highway - it's all very alarming...) and not being willing to pay an expert MB mechanic over $100 for a fluid change, I have (finally!) wisely decided to learn how to do the work myself.

First thing at hand is the engine oil change. I know how to do the procedure, but there's not enough space for me to get under the car to unbolt the drain and let the old oil out. I am thinking of ordering a pair of service ramps, such as the UR6500 (9" high) sold by discountramps.com or the Rhino Ramp 8000 by Blitz (apparently not as high). Any suggestion as to which is best for my purposes?

Though, I need to know first whether by placing the front wheels of the car on ramps, the resulting inclined position of the car will prevent the old oil from being drained properly...
Also, can the ramps be used for doing a transmission fluid change, and (in this case raising the back wheels) a differential fluid change? Will the old fluid drain properly and the inclination angle allow for proper refilling?

I would very much appreciate your advice in this matter...

Rino
