I wasn't - but dug out my GP79 after reading this thread. I gave up on it as it was too hard for my feeble abilities.
I just tried again with the Ferrari and WHOOHOO!!!! :jumping:.
Useless around Monaco [yeah... tried the easy track first

]. But just flew round Kyalami in my fastest time around the track ever. 1.11.584 [I think].
That may not be fast - but it was fast for me. The way you can chuck the car around is unbelievable. I was being too cautious when I tried the Williams. With the Ferrari I had it drifting and bucking around - just using the ground effect to keep it on the track.
Would love a GP79 race around Kyalami some day.
