carbuzz.info - Looking for a proper high-performance Buick? For the previous years, the only choice was Opel-based Regal GS, which has an angry turbocharged engine and large trims. The all-new Regal has come this year, and the new 2018 Buick Grand National successor would be Regal GS once again, but with all-fresh design and new technical improvements aboard. The new car won’t get the legendary name, but in a nutshell, it is 100% successor of the popular muscle car of the golden era. No more cheap V8, long hood and hardtop coupe body – it is a more conventional sedan with V6 under the hood. Is it worse then? Of course not.
