I sure was. In fact, after I created my "new" profile, the old one remained as an option to choose. So, if you ever do get the bug, backup to your cloud, your HDD and a flash and even the game will retain it. In essence, you could have two "driver personalities" to play with.
In any case, I got the MINI relatively quickly. Prices had come down to only $30,000. I would advise getting one Peter. I don't think it will hurt your game and even if it does, you are no worse off since you are not losing levels. Then, grab me or someone (I just created a room tonight and people joined) and run one lappers around short tracks. You will be at Level 16 in no time. I think I got to 31 or something. Far less flexibility on the adjustments, but at least I can tune it.
And I tried some of Boothy's advice and it worked! Well, most of it...like softening up the springs a bit and easing up on the downforce. However my diff is still fairly open and I just could not get used to those higher gear ratios.
Speaking of, I got the same message re: the gearbox about lap 56 or so. It must be just a pattern because I was never hitting the red line.
