 Ive had my 2013 BMW 528i for a little over a year and I love it - best car I've owned.
 Ive driven sports cars and luxury sedans and for me this is a great hybrid of fun to drive and creature comfort.  The 4-cyl engine is plenty powerful for city and highway driving and the fuel economy is surprisingly good.  Its a very comfortable car for daily driving and easily accommodates four adults.  The interior is quiet, comfortable, luxurious, and attractive.  The handling is excellent.  I purchased it from a BMW dealer as a CPO vehicle and I havent had any reliability issues.  
 Overall, the 528i is an excellent car with a great balance of luxury, comfort, sportiness, and fuel economy
