i would drive my sr to oregon and back... no problems... except i might raise it for the bumpy states...
some people have the mentality as soon as they travel with their car it will break.
if the car runs fine in town what makes you think it would run bad out of town? Then again my sr melted a piston @ 430whp in tampa lol.
i agree with this... if it drives fine daily is the same (or almost better ) highway since there is not stop and go... if i keep mine im driving it from miami to alaska!
