Today I traded my 2005 545i for a 2015 535d M Sport with only 28000 miles on it. I had read years ago posts here by e60 535d owners discussing the merits of their car and was jealous of them because it wasn’t available in the U.S. My 545i was approaching 100,000 miles and exhibiting symptoms of the aging N62 V8 that are very difficult and expensive to fix. I am extremely impressed with the performance of the 535d and all the other improvements BMW has made over the years. This car is terrific! It rides smoother, handles better, and has a kick in the seat acceleration I’ve never experienced before. I know the 0-60 is about the same as my 545i, but the diesel gets there in a much more exciting yet almost effortless way. I can only hope the engine is better built and more durable than the N62.
