2006 BMW 5 Series Sedan 525i 4dr Sedan (3.0L 6cyl 6M)
Big bucks German bad transmission cheap parts
 Bought new.Minor problems while under warrantee.Since then, replaced rear wheel bearing at 40K.Transmission slam from second to first like getting hit from behind.BMW engineers created a computer work around for this common problem but will not fix this default and you must pay dealer whether it works or not.Many people being talked into replacing transmission for $5k.Cheap dash components like cup holders and ashtray flimsy, had to replace both two times.For the price paid, quality is severely lacking.Would not recommend buying a used one.Local dealer repair shop is horrible.Had vehicle 9 days on two occasions without fixing.BMW regional tech changed battery 2hrs.
