+              Certificate of Entitlement (COE) Prevailing Quota Premium (PQP)
+              rates are specific to Singapore&apos;s vehicle ownership system.
+              They represent the average COE prices over the last 3 months,
+              which car owners must pay to renew their existing vehicle&apos;s
+              COE.

+            <Typography.P>
+              The PQP system allows car owners to extend their COE for another 5
+              or 10 years by paying the prevailing market rate rather than
+              bidding in the open market. This is particularly relevant for
+              owners who wish to keep their vehicles beyond the initial 10-year
+              COE period.
+            </Typography.P>
+            <Typography.P>
+              The Land Transport Authority (LTA) calculates and updates these
