My take is that it’s always better to buy a used vehicle unless you fall in one of the below mentioned categories:
1) Your usage is really very heavy and involves a lot of travel on the highways. Better to buy a brand new vehicle as you might not know an existing problem in the used vehicle.
2) Diesel Car - If you land up buying an abused diesel car, it might give you much more heartburn than buying a similar petrol version of the same. The very purpose of saving money on fuel will be offset by the cost of maintaining the same.
3) No time for maintenance - If you are seriously hard pressed for time then no use going in for a used car.
4) Company funding (Leasing) - Many companies give their employees an upper limit of buying a car for themselves. If this is the case then buy a new car and drive it well
5) Chauffeur Driven - If you are buying a car which you are never going to drive then its best to buy a new car else the driver will come up with all sorts of reasons because its a used vehicle (my dad's personal experience)
6) Style Matters - It’s really difficult to flaunt a used car, unless it’s been modified to the hilt. Try telling your friend that you have bought a used car & the probability of him being really curious to see it will be low.
7) Long term keeps - There are many of us who would like to keep their cars for at least 5 - 8 years. It’s always prudent to go for a new car in such cases as depreciation will not take a major toll on you. Also you will always know what’s going on inside your car as you would have been with it right from day1.
8) Business Purpose - People buying a car solely for business purpose (read private tourist) should go in for a new car. Simply putting, a new car (especially a new model) will always attract new as well as your existing customers.

Glad if some one can add anything to this.
