Where to dismantle?

The car was in Essex (South East of England). I live in the North West about 225 miles apart. What to do? My in-laws live in Essex so negotiated with them to put the car there while I take off the bits I need. They have an area by the side of the house but no garage so it will be out in the open. We travel down every few weeks so plan to take the MX5 apart bit by bit and transport the parts back up north. Paid for the car with PayPal and found the seller worked for the same company as me (small world!).
