2004 BMW 3 Series Sedan 325i Rwd 4dr Sedan (2.5L 6cyl 5M)
Most Reliable BMW, 2004, 325i
 The 2004, BMW 325i is the most reliable and aggressive engine of the 3 series BMW line. I purchased the BMW in Heidelberg, Germany brand new in 2003 October.Since then, I have not really spent anymoney replacing or changing mechanical parts, except for the rotor, shocks, struts, and of course the occasional oil change.Driving this vehicle is a dream.At 100,000 miles, I just got the transmission and differential oil change. For $36K, it has been the best purchase of this magnitude, ever. The only bad thing about the 2004, BMW 325i is the interior is made very cheap. Stuff start to fall apart after a few years.
