TikZ – Draw a Car Profile

tikz-pgf

I have drawn a simple car with this code:

\begin{tikzpicture}
    \shade[top color=red, bottom color=white, shading angle={135}]
        [draw=black,fill=red!20,rounded corners=1.2ex,very thick] (1.5,.5) rectangle (6.5,2.5);
    \draw[draw=black,fill=gray!50,thick] (3,.5) circle (.5);
    \draw[draw=black,fill=gray!50,thick] (5,.5) circle (.5);    
    \draw[draw=black,fill=gray!80,semithick] (3,.5) circle (.4);
    \draw[draw=black,fill=gray!80,semithick] (5,.5) circle (.4);

    \draw[->,semithick] (0,-.5) -- (0,3);
    \draw (0,3.5) node {$r[x(t)]$};
    \draw[->,semithick] (-.5,0) -- (8,0);
    \draw (8.5,0) node {$x(t)$};
\end{tikzpicture}

And this is the result:

My simple car

There is a simple way to define the outline more similar to a car?

Thanks to all.

    \draw[->,semithick] (-.5,0) -- (8,0);
    \draw (8.5,0) node {$x(t)$};
\end{tikzpicture}
\end{document}
