523i or 525d

Hi,

I am making a choice between these two without being able to test drive either of them.

I am inclined towards the 525d but worried about the noise level and vibration traditionally associated with the diesels (have driven the E60 520d and definitely not impressed). Have read that the F10 diesels are much more refined but would appreciate any real life feedback from people who have driven these - although I know this may be subjective. Was also told that diesels typically get noisier after a couple of years - any truth in that?

The 523i here comes with the n52 engine and any feedback on its power delivery will be appreciated.

Thanks!

Go with 525d. You won't feel extra vibrations etc. These diesels are not the same as they were 15 years ago
