Leon, we could do with knowing what the other "required" car is. Also, there's no stated "meeting point", although I just go to the GPS, target you, and head there, which is probably the sensible plan for everyone.
Could we meet at the light blue spot by the beach?
Oh for GT4/GT5's Photomode controls, eh Leon? Have you looked at the histogram on an MC-LA shot? It's all compressed into the second quartile. Really bad.
