2007 Acura TL 4dr Sedan w/Navigation (3.2L 6cyl 5A)
I recently purchased this as Certified Pre-owned. When compared to its Infiniti G, BMW 3 Series, Lexus IS and Audi A4 counterparts, using such factors as build quality, performance, comfort/convenience and manufacturer's overall attention to detail - all weighed against price - the TL is far and away the best value. It may not be the quickest, most nimble or even the most fun, but it is far above average. The TL is meant for a more utilitarian consumer: high-end without the flash (although still somewhat of a head-turner). Overall a very easy car to drive and the best front-drive you can buy. The 2007-08 TL compares closely to the 2010 TSX V6.
Good mix of power and fuel economy: going from 40 to 80 is fun, cruising at 75 mph still gets 30 mpg. Typical solid build quality of a Honda but with better materials. Nav/Technology is very intuitive. Handles very well for a front-drive. Sound system is excellent. All buttons are illuminated.
Paying for premium gas is a kick in the shorts. Not much else to improve on given the low price tag. I'm guessing the heavier doors serve a purpose for road noise, etc. Also, you must know what you are buying: a sport sedan. If you want a soft ride with cushy seats, then buy a freaking Cadillac!
