About BMW 525i
As a part of the BMW 5 Series, which is seen as the replacement for the BMW New Class coupes, BMW 525i was built by a famous German manufacturing company, Bayerische Motren Werke AG, more known under its abbreviation BMW, between 1989 and 2007 as an executive car.

Competing against the Lexus GS 350, Cadillac STS and Cadillac DTS, 525i had been built through three generations before it was replaced by the other 525 models.
The second-generation BMW 525i (E39) was produced from September 1995 to June 2003 and between June 1996 and April 2004. It replaced the 528i in 1999 model year when the 5 Series was in the fourth generation. 525i was offered in two body styles, 4-door sedan and 5-door wagon/estate and during this generation, it was powered by 3.0 L I6 rated at 189 hp and 181 lb-ft of torque and this engine sent power through 5-speed manual and automatic transmissions to rear wheels.
