Hi Kiran,
Welcome to carwale.com
I generally prefer used cars because it is a lot cheaper. A 3 year old car costs almost 50% of the OTR price of a new one, same model. Which means the same budget can be utilised to buy a vehicle from the next segment.
This translates into multiple benefits as under:
(a) A bigger, better car at the same price
(b) Someone else has already borne the brunt of depreciation. A car depreciates the most in the first 2-3 years.
(c) A well maintained car with proper service records is in most cases a safer bet than investing in a new car. What with all the recalls (not in India so far) and retrofitment of various parts during the warranty.
(d) Todays's cars are good enough for lakhs of kilometres. I've seen many Qualis vehicles with more than 5 lakh kolometres on the odo, still going strong. So, a 3 year old car with 30,000 to 60,000 kms on the odo is no big deal, provided the car has been handled and treated well. That's why inspecting all service records is a must.
(e) By buying a car from one or two segments above, you are also buying a much different experience at the service centre. I got to know about this first hand at a service centre. Besides, the attitude of other vehicles and the traffic constables are also different when they encounter a higher segment car.
Of course, many of us don't like the idea of using a device or gadget used by someone else. Change of upholstery, a good wash and interior cleaning and change of tyres usually does the trick and doesn't cost too much.
Drawbacks:
(a) You need to be very careful and diligent. You may be buying a rotten tomato, especially if you are buying from a used dealer.
(b) The process is lengthy and time consuming. You need time and patience, visting several showrooms, and inspecting several cars, before finalising one.
(c) You need to be flexible on the model / variant. You may have to customise or accessorise after finalising one. More time and effort.
The biggest advantage of buying a brand new car is warranty. You decide on a model, visit two or three showrooms, take a TD, negotiate the best price and drive out from the dealership with the car and a warranty in place.
