As I understand it the car is not registered and therefore you may struggle to prove it ' over 15 years old.
The kit which forms the basis of this car is well over 15 years old though if that would satisfy your import authorities.
Converting the Corse chassis to lhd is fairly straightforward.
You would need to cut out the front bulkhead which mounts the pedal box etc, and turn it round. The custom steering rack will convert by popping put the pinion and reversing it.
Other than that you will need a new dash moulding, but thats about it.
