Confusing stuff.
I have a book by the author of this alleged McLaren 4/4 book and I am now tempted to think most of it was garbage.
I see no reason why Nichols would be lying, Murray is still in business designing all sorts of stuff so stand to gain from being the main man who designed it, but this is all a bit weird, Nichols didn't design much else after this supercar, whereas Murray designed all sorts before and after, but as Steve says the BT55 was a complete and utter disaster but the 89 and 90 cars were OK, so who knows the real truth!
My only thing I do like here is the stuff about the author of this book which is not much to do with who designed it but about the fact the author was up Murrays arse, clearly allowed himself to be led by a charismatic man and the fact Steve and numerous others asked for the changes to be made that clearly never were made. the signees were large in number and the mistakes very many. How this man has continued to write at such a rate is beyond me, he should ahve been signed off after this!!
