Some of the most popular cars for tuners to customize include the Honda Civic, Subaru Impreza and Hyundai Genesis Coupe. Import vehicles of this kind are popular choices for customization due to their relatively low cost and the wide range of factory and custom parts available for modification.
The Honda Civic is likely the most popular customized car of all time as of 2015. The Civic exemplifies the cardinal virtues of a tuner car as it is inexpensive and easy to work on. In addition, the popularity of the Civic among the general public and the long history of Civic customization and tuning means that the parts for almost any customization job are plentiful and affordable.
While the Subaru Impreza and its high-performance WRX derivative are not as well-known as the Civic among most drivers, import tuners frequently use the rally-inspired sedan as a base for customization projects. The Impreza's turbocharged engine is receptive to a number of performance enhancement modifications, including relatively simple engine control unit software modifications that can increase boost and power output significantly. The Mitsubishi Lancer Evolution is a very similar vehicle, but it has never been as widely available as the Impreza and WRX.
The Hyundai Genesis Coupe is a relative newcomer to the tuning scene. First available in 2008, the Genesis Coupe is a rarity among many imports as it uses a rear-wheel drive system. This makes the Genesis Coupe ideal for tuners interested in drifting and motorsport.
