CarSpy
A modification platform for car enthusiasts
What is CarSpy
CarSpy is a car modification platform for a new generation of enthusiasts. Precise part matching, interactive 3D previews and a community of real builds come together in one place — for the curious modifier and the seasoned tuner alike — so every upgrade feels informed, visible and personal.
The right part shouldn’t be guesswork.
Car enthusiasts personalize their cars with modifications like tailgates, wheels and lights. But every car needs different parts, and finding the right one is often confusing and time-consuming.
Find, preview, trust, install
From the first part to the final install.
Five key features keep the whole journey customizable and seamless — from choosing a part, to buying it, to getting it on the car.
Part selection, made simple
Car owners often don’t know which parts fit their car — there are too many trims and specs.
Select your exact car once and instantly see every compatible mod — spoilers, wheels, lights — tailored to it.
Preview every mod in 3D
Modding involves guesswork, in looks and in performance. Owners rarely know how a part will really affect their car until it’s installed.
Preview your exact car in 3D, try mods on it, and see how each part changes the look and the performance — the full picture before you buy.
A community of real builds
Owners lack a trusted place to see real mod results, or to connect with people who’ve done the same upgrade.
Car lovers share their builds, post photos and tag the parts they used — so others can get inspired and learn from real examples.
Ratings and reviews
Photos and product descriptions can’t tell you whether a mod is actually good.
Every product carries detailed ratings from real owners — quality, fitment, looks and more — and a total score for a quick verdict.
Installation support
Many owners don’t know how to install a part, or where to find a shop they can trust to do it.
Follow step-by-step video guides, or book a top-rated local body shop and just bring the car in.
Owners want to see it before they buy it.
To find out what a different kind of parts site should do, I interviewed car owners about what they want, what they need and what holds them back.

Three things to design for
Easy to buy, hard to trust.
To position CarSpy and its audience, I analyzed three established aftermarket retailers — what they do well, and where owners are still left guessing.

Easy to buy, personal to your car
Ease of purchase against installation aids; an open community against personalization. CarSpy aims for the top-right corner none of them owns.
One car, four paths.
Everything starts with choosing your car. From the homepage, four flows cover the whole experience — from picking the right part to getting it installed.

Logic first, then look.
Low-fidelity wireframes settled the interaction logic of the whole site first. Mid-fidelity screens then brought in real cars, parts and photos.
Low fidelity
Mid fidelity
Dark by default. Lime for action.
A dark interface with one signal color: lime #CAEB54 marks selection and action — Select, Save, Get Started and the active tab.
Design system
Poppins throughout, from Black to ExtraLight, on a 16 / 20 / 24 / 32 type scale. Lime #CAEB54 is the only accent; #3D3D3D, #262626 and #19191A build the surfaces.
