Have owned 5 series since '85 - 528e, 535is, M5, u name it. This car has been the best of the lot. Beautiful classic exterior and interior lines - 2.8L is BMW's most reliable in-line 6 with plenty o' power (yes the M5 clearly is the pocket rocket, but 2.8 can get up and go and is easier on the gas guzzling.) The E39 is also the last 5 model without the ridiculous iDrive computer, which is completely unneccessary for driving, a safety hazard and blight on the dashboard. No major repair issues to date. When this stops running, I'll buy another used E39.
