2007 Acura TSX 4dr Sedan w/Navigation (2.4L 4cyl 5A)
Plenty fast enough for daily driving, gives me an average of 33 mpg at 75 mph cruise control on long drives. It's not necessarily "sporty" compared to actual sports cars. It has stone hard economy tires and a soft luxury suspension. So take it for what it's worth or upgrade your tires and suspension. Looks are subjective but I still think it looks nicer than most cars even after the 4 years it's been in production.
The navigation is great. Solid and acurate steering response. All the controls are placed very intuitively to easily do whatever you want. Fun to drive, quiet and comfortable. It's a humble luxury car.
