So lets lay this out...
You want to put a 1j which can pull over 200 no sweat, into a old rusted car (all old cars have rust carnt get away from it)
You want to then push the 1j on the roads where there are any number of unknown variables
Then there is your skill level, at 19 it's limited maybe the story would be different if you were a know hi-po race driver but I'm fairly certain you are not, especially with an attitude of "nooo wayyy broooo I'm 2 skilllleezzed to crah"
