5. Marry: 2014 BMW 3 Series
BMW’s 3 Series has been so good for so long that it’s become a blue-chip stock in the automotive industry; it’s like driving a share of Class-A Berkshire Hathaway. It’s literally a car you could own and enjoy every single day for the rest of your life, it’s that good. The 335i is one of our favorites. This sedan is a dream to pilot with a silken 3.0-liter, turbocharged inline-six that pumps out a claimed 300 hp. The engine can be paired with either an eight-speed automatic transmission or a super-satisfying six-speed manual. Do yourself a favor, propose to a 3 Series.
