Hi,
Thanks for the answer. I have tried to get somebody from Toyota (Lexus) maintenance to give me an estimate about this conversion but haven't heard back. What is the company that you used in Blackpool? Do you have some sort of idea how much these modification should cost?
I got actually a pretty good package offer from these guys:

Can't find so much information about that company.
