I have had my 528 since July of this year, and love it!! It has 101k on it and is a blast to drive. Everyday I look forward to the commute to and from work as it is my unwind mobile! I average around 26-28mpg combined, yet it has snappy off the line and low end torque. Mine has the 5-speeds which is what I was looking for. Only maintenance problem was a broken motor mount ($40) done myself, relatively simple repair, and a rear window regulator ($95), again, did it in 1hr!! The fit and finish of BMW's has always impressed me, and the 528 does not disappoint!! People gripe about the cost of parts, but that's a fair trade off for a quality, well-engineered car that is designed to perform!!
Though it's 11 years old, does not look or behave like it!! Classy interior, 5-speed, performance, handles like it's on rails.
