One of the A4's biggest strengths is that it appeals to luxury shoppers in a number of ways. If you're concerned about gas mileage, it's comparatively thrifty. If you like fine furnishings, the cabin will feel like home. Plus, there are a number of available high-end features to interest technophiles. It may not offer the pure driving experience of a 3 Series, but in the areas that matter most in this part of the luxury segment, the entry-level A4 stands tall.
