Best advice i could give you mate would be to go threw and importer. Such as dunc at fast jap cars very local to this site i bout mine off him very friendly guy and you got jm-imports thats just 2 i know that iv know are good. or another option just get one from ireland there's alot of good ek9's coming from there latly hope this helps mate
Torque gt in Devon also do them fairly often.
After your comment regarding them being a 12 year old car and the seller being a comedian, seems strange you now want to splash out even more importing one.
