2. Problem Statement
The process of buying and selling cars is inefficient, costly, and time-consuming. Traditional
methods, such as relying on third-party dealers, intermediaries, or scattered online platforms,
present significant challenges for both buyers and sellers. Buyers face difficulties in finding
reliable listings that meet their specific needs, often spending considerable time browsing
unorganized or incomplete platforms. On the other hand, sellers encounter hurdles in reaching
the right audience, verifying serious buyers, and efficiently managing inquiries.

Furthermore, third-party intermediaries frequently add unnecessary complexity and costs to the
process, taking away from the transparency and trust needed for a smooth transaction. For
buyers, this can result in higher prices or limited choices, while sellers may face reduced profits
due to commission fees or delays caused by the involvement of middlemen. While intermediaries
often claim to facilitate transactions, they frequently complicate the process by introducing
additional costs, delays, and unnecessary paperwork. Buyers are often forced to pay higher prices
due to intermediary fees, while sellers are left with reduced earnings. The reliance on
intermediaries also limits direct communication between buyers and sellers, creating barriers to
transparency and trust. Additionally, a lack of secure communication channels, unverified car
listings, and the absence of advanced filtering tools exacerbate the frustrations associated with
car trading. These issues not only waste time for both parties but also create an environment
where trust and efficiency are compromised.

There is a clear need for a centralized, user-friendly, and secure platform that directly connects
buyers and sellers, ease the transaction process, and eliminates the inefficiencies associated with
traditional methods. These issues highlight the urgent need for a modern, user-centric solution
