I am really confused about buying a car right now. My limit is 30 to roughly 45,000 dollars. I want a car with bluetooth navigation system and parking assit device. I hear that the navigation system in the volvo is not good. Is that true? Basically I do not know what to get. Right now I am leaning towards a volvo but torn between this and the BMW 3 series, Mercedes c class, and an acura TL. Please can someone help me. Thank you!

Only the BMW 5 series and Mercedes E class could compete with the Volvo S80. I'm pretty sure if you consider all aspects and features of the car, the base S80 would beat the BMW 3 series and Mercedes C Class hands down.
