First of all guys wow my login still works after 5 years. lol. but i wouldnt give Forza too much credit for tracking the cars you use. It has many flaws in its system too.
Unfortunately im a traitor since i am now a Forza player but i hope you will listen to what i have to say anyway.
Forza's car logging system leads alot to be desired since it lacks local leaderboards! With no internet you have no way to keep track of any of your laptimes! you still get a ghost but its just not the same.
On the otherhand it does log what you do in each car, ie parts value, races raced, wins, podiums and distance driven but thats about it. far more detail could have been put into this section but they didnt.
And finaly i miss the good old save/load ghost option in the menu from gt3/4. surely this would be a good idea in both games (dont own gt5 so dont know if u can still do it). this would mean you could send a friend a ghost.
The real question is tho, when will everybody realise that Turn10 & Polyphony Digital shoud team up and make an uber driving simulation with all the best parts from both games. i mean personally while gt5 is very pretty in my opinion the graphics are less important, i means i would probably go back to gt4 graphics if the game engine was a replica of our physics system (ie perfect physics in every way). And i now live for online racing because the AI in forza is way too easy and online is the only place to get a close race.
Anyway sorry for the rant guys but i thought id explain about forza
