While I wish then well, launching a new car is a bit of a stretch for the Goodwood Revival...a new TVR hasn't got a huge amount to do with pre'66
Similar comments have been made in the Goodwood forum. Actually around the periphery of the "Earls Court Motor Show" exhibit there are always a handful of manufacturers who bring their latest models. I imagine the cost of having a stand there is pretty hefty.
