1 INTRODUCTION

In the used car marketplace, buyers and sellers often

face challenges such as inefficient listing processes,

unreliable search results, and a lack of transparency

in transactions. These issues can result in prolonged

delays, reduced trust, and an overall suboptimal

experience for users. Current platforms are scattered

and require users to rely on fragmented information,

making it difficult to navigate the process of buying

or selling a vehicle efficiently. Our proposed solution,

The Trade Wheels, addresses these issues by

developing a streamlined platform that connects

individual car buyers and sellers directly. The

platform offers tools to simplify the listing process,

enhance search and matching capabilities, and ensure

secure and transparent transactions. User feedback

from real-world scenarios indicates that existing

platforms fail to adequately meet user needs due to

outdated features and cumbersome workflows. The

Trade Wheels aims to revolutionize this space by

creating an intuitive, feature-rich marketplace that

improves operational efficiency and user satisfaction.

2 OBJECTIVES

Architecture for the Web and Beyond, intuitive

design and usability are critical for driving user

engagement. However, implementing effective

filtering and matching algorithms for products like

used cars introduces challenges, including data

standardization and real-time search optimization

(Jones & Smith, 2020). Addressing these challenges

is essential for delivering an inclusive and efficient

marketplace.

Kumar and Patel (2021) highlight the importance

of secure transaction systems in building user trust,

especially for high-value goods like vehicles. Tools

such as integrated payment gateways and user

verification processes play a vital role in ensuring the

credibility of online platforms. AI-driven search and

recommendation systems further enhance user

experience by anticipating needs and providing

relevant results (Gupta & Sharma, 2022).

The scalability and reliability of digital platforms

are crucial, particularly during periods of high

demand, such as seasonal sales or promotional events.

Cloud-based infrastructures ensure that platforms can

handle increased traffic without affecting

performance (Kaushik & Gupta, 2022). Features like

advanced search filters, predictive analytics, and real-

time data updates improve accessibility and

personalize user experiences, ensuring seamless

interactions for buyers and sellers alike.

The Trade Wheels builds on these advancements

by integrating modern technologies, ensuring a

transparent, secure, and user-friendly platform

tailored to the unique challenges of the used car

marketplace.

4 METHODOLOGY

4.1 Existing System

The existing process of buying and selling used cars is

disorganized and inefficient, relying on multiple

disconnected steps. Figure 1 shows the existing

system block diagram.

Figure 1: Existing system block diagram.

Sellers typically list their vehicles on various

platforms or classifieds, often repeating the process

on multiple websites to gain better visibility. Buyers,

on the other hand, must manually search through

scattered listings without effective filtering or sorting

options, making the search process time-consuming

and frustrating. Price negotiations occur informally,

often leading to misunderstandings or disputes due to

the lack of transparency. Payments are handled

manually, with no secure gateway to ensure safe

transactions, leaving both parties vulnerable to fraud.

Additionally, the process of vehicle inspections,

document verification, and ensuring legal compliance

is entirely manual and requires significant effort from

both buyers and sellers. These inefficiencies result in

delays, frustration, and a lack of trust in the

marketplace. The final steps of the transaction,

including payment and legal documentation, are

ICRDICCT‘25 2025 - INTERNATIONAL CONFERENCE ON RESEARCH AND DEVELOPMENT IN INFORMATION,

COMMUNICATION, AND COMPUTING TECHNOLOGIES

handled manually and separately from the initial

interactions. Payments are often made in cash or via

basic electronic transfers, which lack the security

features necessary to protect against fraud. Similarly,

document verification, ownership transfer, and

compliance with legal requirements are left to the

discretion of the buyer and seller. This adds additional

time and effort to the process, as both parties must

navigate complex procedures without any integrated

support from the platforms they used to connect.

• Pros of Existing System: The structured

admission process offers clarity and

transparency, with clear expectations at each

step. Parent orientation ensures families are

informed, while the entrance test and

interview maintain academic standards by

admitting qualified candidates. The defined

timeline, including a three-day waiting period,

helps both applicants and the admissions office

prepare for subsequent steps.

• Cons of Existing System: The admission

process involves delays, multiple interactions,

and waiting periods, causing anxiety for

applicants. The three-day wait for test results

adds uncertainty. Applicants must manage

several steps independently, which can be

overwhelming. Additionally, the process lacks

flexibility for those requiring special

accommodations, reducing accessibility for

diverse applicants.
