I purchased this car about a year ago and so far, no complaints. I originally test drove a Sentra, Civic, Corolla and a Mazda3 before buying the Focus. The Focus just felt a little more solid and very quiet on the inside. The Focus lacked pep, but after a year of driving, I think it's gotten a little quicker now that it's broken in. After a year it is still very quiet, no rattles or squeeks. I have had no problems whatsoever and I am definitely glad I purchased the Focus over the competition. It is a well built car, fun to drive, has great features, and was very inexpensive. $16,700 out the door!
Sync is well worth the $$$. I like my 16" wheel option and the fog lights on the SE. I also like the cavernous space under the armrest and the 5 cupholders. Larger trunk than most cars this size.
