The very first thing that you should decide is " how much is my budget ? " , then fix the amount that you pay for the new vechile. Before walking into a dealers showroom, do a market survey to find out the vechile that suit your budget, also understand its specifications, performance, mileage, maintenance cost, comfort, safety and service networks also .Online searching will help you to narrow down your search for a perfect vechile.Read experts and independent reviews ,comments and analyze them. Always compare vechiles of same segment.
Taking quotes from different dealers is a good idea ,do the same from insurance companies also.Ask the dealer for written quotes,so that ther is no misunderstanding if you decide to goahead with the deal.
Before bargaining you should have a clear understanding about your needs and rights.Usually dealers have monthly and quarterly targets set by the vechile manufacturers..so, inorder to hit the targets they often give additional discounts and offers at the end of the month or the end of a quarter (march,june,sept & december) .Most customers are not aware of dealers monthly and quarterly targets set by the vechile manufacturer.by keeping all these on mind use your bargaining and negotiations skills.
Before buying ,understand the standard features and additional (optional ) features of the vechile,dont spend money for some optional features which are not really useful or required.
Comming to warranty part, understand each and every details about the inclusions and exclusions in warranty contract.Be careful while opting extended warranty,because they are not transferable between dealers, due to this a customer cannot able to service his vechile with another dealer.
By keeping all this on mind always take a wise decision before buying your dream vechile.
All the best... Happy journey ,Drive safely..
