Having used the GSF website to identify the parts we required we were disappointed to find that the sump was not compatible with the one fitted to the car - and the gasket ordered didn't either, in fact it didn't even fit the ordered sump!!! We therefore lost confidence. So whilst the discount offered gave a competitive part pricing the parts were of no use. To keep thing simple we returned all the parts within the order - and things aren't simple here either. Returning the parts to a local store basically didn't give us a refund - we now have to wait for the local store to return the parts to the web site store and at that point hopefully we will be refunded. Thus even though the prices at the local stores are significantly higher, am not sure we will be using the web site again.
