I am currently looking at several used 2007 M5s - One with 6-sp manual - the rest have SMG. I am concerned about reviews from owners that their M5 consumed excessive amounts of oil early.

I had a 2000 540i 6 speed and never added oil between changes - I had been told that there would be some consumption but I never experienced it. I have a 2004 X5 3.0 6 speed and add about 1 quart every 3000 - 4000 miles - supposed to be normal consumpton for that engine which now has 40,000 miles on it.

I have read multiple negative comments about the M5 re: MPG, SMG, etc. But I know that if I had paid full attention to negative reviews I would have never bought the 540i or the X5 and I love both.

I assume most owners love the car - any thoughts on the oil issue? I am asking because now is a good time to buy used - 07's are available at 40% or more off original MSRP.

Thanks
