I think the 300C is a very attractive car. Despite the fact that Lexus is more reliable, we cannot overlook the appearance of 2001-2003 LS430, which are not as attractive as the 2004. This is the view of majority of people who have participated in the forum not just my opinion.
As for new versus old, as a student a new car is not even on my list!
BUT, if I can ever afford a new car, I would greatly love to go the extra mile and purchase it new. There are few things that I do not care for to be used or new. As a car lover, I would like to have a car build just for me, for once I do not have to look in papers, lots, etc., in hope to find something that I want. I can just pick and order whatever I desire.
