Who We Are
The Grand Istanbul Bus Terminal is the centre of the coach business in Türkiye. We have been inside that centre, in the spare parts complex, doing the same job since 1998: finding parts for intercity and city buses.
This trade is not about selling from a catalogue. When a coach breaks down, or something snaps just before departure, that part has to be found today. That is why we keep 1,953 different products on the shelf rather than ordering them in.
Most of our customers are bus operators, service workshops and fleet businesses — in Türkiye and increasingly abroad. They stay with us because we deliver when we say we will.

The Rules We Trade By
We don’t ship the wrong part
Nothing leaves before make, model and year are confirmed. If the mistake is ours, so is the cost of putting it right.
We quote a firm price
OEM and aftermarket priced side by side. No surprise line items later.
On time, as promised
No “we’ll look tomorrow.” In stock means today; out of stock means a real date.

From Istanbul to Anywhere
Our shop is in Istanbul but our customers are everywhere. We ship to all 81 provinces of Türkiye and export worldwide through DHL, UPS, TNT or your own freight forwarder. Orders placed before 4:00 PM are dispatched the same day.
For export orders we prepare the commercial invoice and packing list required for customs clearance, and can consolidate multiple items into a single shipment to keep freight costs down.
