Auction Items
All auction items are imaged and described as good as possible. Please feel free to email with any questions you may have. We try our best to answer all emails as quickly as possible.

If purchased, all mechanical items like motors and transmissions should be disassembled and inspected. Please review all images of the item. The images are considered a continuation of the item description and most times can provide better information than any written description.

"Freight Collect" is a term used in the freight moving business that means that the freight will be paid by the person receiving the freight.

When shipping international FOB is defined as "Free On Board".
When shipping within the continental United States FOB is defined as "Freight On Board".

In either case the term FOB is used with an identified physical location to determine:
1) The responsibility and basis for payment of freight charges.
2) The point at which title for the shipment passes from seller to buyer.

When items are shipped international, via freight, the definition of the term "FOB Garden City" means the buyer pays for transportation of the goods from Garden City Michigan to the port of shipment, handling charges, loading costs, ground / ocean / air freight transport, insurance, unloading, taxes, duties, port charges, and transportation from the arrival port to the final destination.

When items are shipped within the continental USA, via freight, the definition of the term "FOB Garden City" means the buyer pays for transportation of the goods from Garden City Michigan, insurance, unloading, taxes, dock charges, and transportation from the arrival dock to the final destination.

As outlined the term "FOB Garden City - Freight Collect" has the following meaning:
The buyer pays all freight costs.
The buyer bears all freight charges.
The buyer assumes title and control of the goods the moment the carrier signs the bill of lading.
The buyer assumes risk of transportation and is entitled to route the shipment.
The buyer is responsible for filing claims for loss or damage.

If you opt to arrange pick-up, British Only will require the courier to sign a pick-up contract which will outline the condition of the item(s) at the time of pick-up.

Our Goal Is 100% Customer Satisfaction !!!

Refused Shipments

Shipments returned marked refused, or not in when driver called, will cause the refusing customer’s buying status to be frozen. No more shipments will be possible until all freight and handling charges are paid in full. Refusal of a shipment does not relieve the customers liability for paying these charges. Repeated returned shipments of this type will cause the customer’s buyer status to be permanently revoked.


We are not responsible in the event the shipping company makes an error, loses a package or a package is damaged. Any shortages or discrepancies must be reported within 10 days of receipt of delivery. In the rare case that you receive a damaged package, you MUST advise the delivery service and/or customs agent of the damage at the time of delivery. Failing to note that the package is damaged at the point of delivery may void any future insurance claim that you may need to file.
