Diesel or Petrol?
Big car or not?
Sporty or classic? Station Wagon?
Personally, I like BMW's. I have a Skoda Octavia Combi TDI which is a pratical and logical choice. Good value for money. High mileage, 140hp, lots of space.
I have a BMW, also diesel, that I bought 8 years ago, all new. After 180.000 miles, it went for repair shop for a proper maintenance. Zero problems so far. Better chassis, the engine is smoother than the Skoda but probably not as fast. Not so smart buy because it was considerably expensier.
But if you want something out of ordinary, you should go with a Volvo or a Lexus or even a SAAB.
The Mondeo is also a great feckin' car, which isn't as valued as it should be. A Citroen C5 with the hydractive is a hell a of a car also. The Subaru cherish the boxer engine and the 4WD and they are sweet.
A lot of cars can fit the bill mate. Be more precise about the things you value in a car.
