I need the boards help. I'm trying to decide between the above cars. The 540 6 speed has 30,000 mi with Dinan cold air, chip, exhaust still 6 months under fact warrenty I think I can get it for around $34000. The M5 has 64000 mi, not quite as good of shape as the 540 for $38,000. I love the idea of owning an m5 but it felt a little brutal to drive daily (wife would also drive the kids around in it) over the 540.

Concerned about maintenance with the M5( coming off of a terrible experience with an 8 series), no spare etc but still drawn to it. Also concerned about depreciation. Not worried about the money as much as the depreciation as I like to change every few years.

Any thoughts..

Thanks for any advice.
