Jon,
I am in the process of importing a car through an import company in Teeside. It will be here in about 4 weeks - so far their service has been exemplary but I would rather not name them or give a decisive recommendation until I have the car in my grubby mits. It is a '92 R32 GTS-t manual, Grade 4 and I have paid less than £4.5K all in....
If you are still interested in a few weeks, drop me a PM and we'll have a chat.
Laters,
Pad
