Car warranties are basically another form of car insurance. They pay for the damage in case of accidents but off course they don’t happen more often. Car warranties are more commonly bought for psychological reasons than for financial safety. No matter what most companies publicise, on average, they expect to make money selling warranties rather than benefiting the buyer. Obviously, that won’t happen if they pay more for damages than they earn from selling warranties. So, if you have saved up enough for emergencies, you should preferably consider avoiding warranty.
On the other hand, if you perceive the idea of used cars being more prone to damages, you should go for the warranty and rid yourself from daily headaches of paying large bills. Even if you have made your mind, you should consider other factors as well because different companies offer different coverage options.
What car components should be covered in plan? If you have some mechanical knowledge or you have found problems in the vehicle history which are specific to certain parts, you can opt to buy powertrain warranty which generally covers engine, transmission, drive axle etc. It will keep you from spending unnecessarily and put your mind at ease.
How much is the deductible? Is the specific repair shop far from your location? etc. Your goal while buying a car warranty is to maintain a balance between your financial constraints and your peace of mind. You have to make sure that you are not paying for something which is not absolutely necessary.
