Part Selection Made Simple
Problem
Car owners often don’t know which parts fit their specific model due to the wide variety of trims and specs.
Solution
Select your exact car model to instantly see all compatible mods—like spoilers, wheels, and lights—tailored to your vehicle.
Feautre
Carspy's five key features provide users with a highly customizable and seamless experience from the moment they select an item to the moment they purchase it.
3D Preview for Easy Modification
Painpoint
Modding often involves guesswork—not just in appearance, but in performance. Users rarely know how a part will truly affect their car until after installation.
Solution
Preview your exact car in 3D, test different mods visually, and see how each part changes the car’s look and performance. From styling to speed, get a full picture before you buy.
Community for Car Enthusiasts
Painpoint
Car owners often lack a trusted place to see real mod results or connect with others who’ve done similar upgrades.
Solution
A space for car lovers to share their builds, post mod photos, and tag the parts they used—so others can get inspired and learn from real examples.
Ratings and Reviews
Painpoint
It’s hard to tell if a mod is actually good just by looking at photos or product descriptions.
Solution
Every product on CarSpy comes with detailed ratings based on real user feedback—covering quality, fitment, looks, and more. A total score helps users quickly judge if a part is worth it.
Installation Support
Painpoint
Many car owners don’t know how to install parts themselves or where to find a trusted shop to do it.
Solution
Need help with installation? Watch step-by-step video guides or let us connect you with a top-rated local body shop—just book and bring your car in.

User Research
In order to know how to create a different kind of car modification parts website, I did user research to help me create the car website.
While the website provides a convenient purchase process, it also needs to let users know how the physical installation will look like
Create a My Car interface that is specifically designed to help users customize their car
Provides a community interface that contains feedbacks and reviews from other users, as well as various videos of the installation process.
-Be able to purchase different mods in the website
-Be able to see the effect or model of the modification before install the mods
-Don’t know how to install
-Fear of buying unfit modifications
-Fear the mods doesn’t match expectations
-Need to purchase the mods
-Need after-sale service help
