Need to represent a moving car through a service center in beamer. A motion is depicted on the link How to make the length of a car moving on a roller coaster track remain unchanged?. Need a similar type of format. The car needs to move to service center and then leave and this movement should go on.

I have tried the following:
\documentclass[aspectratio=169]{beamer} % Document class
\usepackage{subcaption}
\usepackage[english]{babel} % Set language
\mode<presentation> % Set options
{
\usetheme{default} % Set theme
\usecolortheme{rose} % Set colors
\usefonttheme{default} % Set font theme
\setbeamertemplate{caption}[numbered] % Set caption to be numbered
}
\usepackage{tikz}
\usetikzlibrary{tikzmark}
\usetikzlibrary{overlay-beamer-styles}
\usetikzlibrary{shapes.geometric, arrows}
\usetikzlibrary {arrows.meta}
\begin{document}
\begin{frame}{Example}
\begin{tikzpicture}
\draw[black, thick] (0,0) rectangle (3,2) node[pos=.5] {Service center};
\draw[-stealth] (-3,1) -- (0,1) node[midway,above] {Car};
\draw[-stealth] (3,1) -- (6,1) node[midway,above] {Car};
\end{tikzpicture}
\end{frame}
\end{document}
