All separate car brands are made differently by different designers, engineers and developers. Some are made with higher quality material and some are more advanced in their research and development process, making their vehicles superior to others. Before you buy a used car, it is in your best interest to learn which automakers and their cars were built for reliability and longevity. When buying used you save several thousand dollars, though it can be a gamble if you have not done your research.
Warranty Direct has released a Reliability Index which lists the vehicles that have proven to rate the highest when it comes to how often any given vehicle needs repairs, the cost of those repairs and how long it can go without needing repairs.
The used cars at the top of the list include the 2001-2008 Honda Jazz, 1999-2003 Toyota Yaris, 2006-present Mercedes-Benz E-Class, 2005-present Mazda MX-5, 1996-2004 Volvo S40, 1998-2006 Honda HR-V, 2005-present Toyota Aygo, 1997-2006 Suzuki Alto, 2000-2008 Vauxhall Agila and 2005-2008 Mitsubishi Lancer.
