@thekentuckygent not yes and no. It’s a no 100%
Don’t mean to sound rude.
Just got a email from Google about such an issue.
The website you linked as an example FAILS the “Google Mobile-Friendly Test” 100%. So you will be penalized and your mobile SEO will take a huge hit. Unless you make it responsive.
Don’t believe me? Sign up for Web Master tools for that website and I can guarantee you will get an email regarding your site. It will be a warning about your website not being mobile friendly.
Responsive is mobile friendly.
Still don’t believe me?
Check out the website for your self on the “Google Mobile-Friendly Test” (I linked below)
https://www.google.com/webmasters/tools/mobile-friendly/?url=www.grasiemercedes.com
then try a responsive website and watch it pass with flying colors.
