However, some consistently popular platforms often cited include:
* Honda Civic (especially older generations like the EK, EG, and DC): These are extremely common, readily available, and have a massive aftermarket support network with affordable parts. This makes them a very accessible entry point for tuning.
* Honda Integra (especially the DC2/DB8): Similar to the Civic, the Integra shares the same platform advantages, but often commands a slightly higher price due to its sportier heritage.
* Nissan 240SX (S13/S14): This rear-wheel-drive coupe has long been a favorite among tuners for its drivetrain layout and relatively affordable price.
* Mazda Miata (MX-5): The lightweight and nimble nature of the Miata, plus its large and dedicated community, makes it a very popular platform for tuning, particularly for handling modifications.
* Subaru WRX/STI: These cars come with a performance-oriented foundation, making them popular choices that are already set up to handle tuning upgrades.
The "most common" really depends on the specific criteria used and the geographical location. Any of the above could legitimately be considered contenders for the title, depending on the context.
