I drove my lovely smartcar onto hard, rough surface road, accurately unpaved road. Because of solid suspension of smart, I gave up driving on that condition in a few miles. More than anything else, numerous bumps made my own smartcar creaking at rear, driver seat side. I was afraid bumps shaked up and down engine and misc. therefore, the nuts and bolts may have been loosened.
Smart sounded plastic creaks as these frictioned each other. Do you have any idea to remove potential creaks? Will mine be stable despite a few miles driving on unpaved road? of course, the rocks or sunken ground never damaged mine.
I expect your experience and experitses.
