And now, the end is near.
The final day of 2023 Formula 1 pre-season testing is upon us - with lots of questions still to be revealed before the season-opening Bahrain Grand Prix next weekend.
Just how fast is that Red Bull? Are Aston Martin as good as they look? What on Earth happened to Mercedes on Day 2?
Zhou Guanyu was a surprise fastest on Day 2 with a late glory run, but it is Max Verstappen who has stamped his authority on this test - although he won't be driving today having got through his one-and-a-half days allocation.
But what will happen as on the final day of testing? Will everyone find the answers they need or be left scratching their heads even further?
