Never happened to me before, but since the update, I have missed like 3 races because I find myself in a very slow car in the race or a bad starting position and realise it is because my car is not repaired nor engine changed. Basically you can't play this game if your car and engine are not at 100%, so I would like any kind of BIG alert whenever you car is not fitted cause I'm annoyed of missing races like this.
Actually the engine and car repairing is useless since everybody goes to every race with it at 100% (otherwise you just don't bother race cause you are stupidly slow). So it is either removing this feature that is just annoying and not fun in any case or then just at least make a clear big indicator of when your car is not fitted cause since the update happened to me several times already and there's obviously a pattern there. Thanks.
