Lol.  This is hilarious.
Ok, I haven't played 4 yet, but I'm about to buy it.  I'm an AVID fan of the Gran Turismo series.
THRAWN - In GT3, you start out with 16,000 dollars.  That's JUST enough to get you either a Beetle, or a PT Cruiser.  Yes, you heard right.  A beetle or cruiser.  Those are the HIGH-end models to pick from at start.  Now, the first time playing through, I raced the same track about 30 times, JUST to get myself enough money to buy a Viper GTS.  It took a bit, but I did it.  Sometimes, I'd only get 2nd or 3rd place, but I managed to get better.  Later, I fiddled with the MODs of the cars, and realized what I could add and change.
I proceeded to whoop butt, soon.  I have beaten every part of GT3 except for the F1 mode, where I still have the game saved, mid-tourney.  I haven't the nerves to do that, quite yet.  :p 
Just take your time, experiment.  It's like when you first start driving, or editing.  It takes time, and you KNOW that.  I was equally as frustrated as you (without obliterating controllers, but managed to fault one out) by GT3, and told my friend the game was stupid, so I quit playing it, and refused to do so when he challenged me.  Later, I bought it, pwn3d at it, and now he refuses to play when I challenge him.
AT LEAST play the game for it's engine.
