DD2, my favourite racing game ever ! I didn't play stock car mode much though, and this mode's speedrun is quite a challenge in "all races" category : finishing every track is sometimes hard. And the hardest races to finish (in my opinion) are Liberty City and Ultimate Destruction Speedway... which means the last ones you get to play in divisions 1 and 2... so you can destroy your car, and your run just before you achieve it ! Still, I really enjoy DD2 speedrun !
