hello,
i have something that you need exactly for such a website,
so make sure to give your time to read my message carefully,
firstly have a quick look at my feedback,
i have good experience in php , that is required to make your website,
now, next is, i already have 4-5 scripts on different platforms,
so no need to waste time on building a new one,
the best part is they are seo optimized,
have mobile versions too,
and you easily add/remove cars,
and many other features.
i can provide you demo,
so let me know if interested
thnx
