Getting breakdown coverage abroad can be expensive enough in itself, and you certainly don't want to pay any more than you have to in order to ensure that you are adequately protected from damage or accidents when driving in other countries.
A good way to narrow down your search is by seeking out foreign car insurance companies that specialize in providing policies to drivers that are in your age range, or gender, or those who drive similar types of vehicles as you do.
If your primary concern is saving on the costs of foreign car insurance, you way want to steer clear of companies that have extensive advertising.
These companies are generally more expensive, which does not necessarily translate into better service or more extensive breakdown coverage abroad.
A bit of comparison shopping around would be in order here, and you should be able to get adequate coverage at a price that fits into your budget.
That being said, the price should not be the only consideration when shopping around for breakdown coverage abroad.
You don't want to be in the position of finding out that you are not adequately covered in any situation, but especially not when you are traveling alone in what may be an unfamiliar country.
Take your time and don't settle for the first overseas auto-insurance company that you come across, and you should be able to get a plan that protects you without breaking the bank.
