Very impressive car. No regrets about buying it. Averaged 36 MPG for the first 1,000 miles consisting of a mix of city / highway driving (30/70). Well built, fun to drive and great looking for a compact car. I am 6'2" and the car is comfortable for me. There is plenty of room. Looking forward to getting 40 MPG on highway trips. I strongly suspect it will be in the 40's once it is broken in and I have a chance to get it out for highway only driving. At 65 MPH, the engine only turns 2,100 RPMs which is incredible for a 1.8 - Liter engine. Also the 140 HP generated is impressive.
Love the dash / instrument panel with the digital speedometer. The 5 speed automatic transmission is very smooth and economical. Like the idea of driving a green car. The '06 Civic is an Ultra Low Emissions Vehicle.
This car really does not have any downside. The only thing I can think of is I would have liked a few more small interior storage compartments. A sunglasses compartment would be a nice addition.
