For those of you hanging on for 300 ST orders, some of mine post/pre-drive this morning as long overdue (plenty of clean pictures on here, this is one with a decent drive behind it - has held up well).
500 miles in and very happy with it. Finally got around to some progressive driving last night; not full throttle as still bedding the engine in. What I do most is balanced and progressive driving. Acceleration through selecting the correct gear and boost could still be comfortably achieved with about 2/3 throttle. It's something I really like about this car, it's capable of relaxed driving through to smooth progress, though you can open up very easily. I firmly echo the comments that it handles like it's on rails, but wary of relatively high centre of gravity when carrying progress.
Had plenty of compliments on this car lately too, it's shaping up to be a decent long-termer.
