6 types of used cars to avoid at all costs, according to an expert

Buying a used car is not always the right bargain that most people expect to be it.

On the one hand, the interest rates of used cars are exceptionally high these days. According to data from Edmunds' automotive industry experts, the current average rate is 9.5% on average, the highest ever since 2009.
