I prefer actually owning cars. Leasing is good if you don't like caring about your vehicle and are okay with always having a car payment. Buying used has its risks but if it turns out good you won't regret it. Buying used is the best if you have the money and are looking to have a long-term commitment with the vehicle. Also buying used and new gives you the ability to always sell later on.
Buying a new car is the worst investment ever, the price of new cars depreciate very quickly.
I don't really see it as an investment for exactly that reason. It's a necessary expenditure for life, and with buying used my concern is that it will depreciate significantly faster because of multiple owners and all that. But the lower cost is appealing.
Das, what's going on with that profile pic?
New. No contest.
