If got any hybrid, mild hybrid just get out from it. Even non hybrid merc also got a lot of issues nowadays, just think about adding more components... Numerous complaints nowadays, unless your getting pure EV most other cars from them really bad nowadays.

Not to say bad, but merc nowadays the interior really like lala bang car (those interior LED, u know what i mean), If you go touch their interior plastics really feel cheap. If you ask me which car feel more luxury, mature nowadays is Lexus, furthermore their reliability also win Merc far ahead..

If you say pure EV I will agree Merc is in the lead.
But if ask about Toyota/Lexus hybrid (Which the latest GLC is a hybrid also) is way more better (efficient) & reliable than merc anytime.
Merc can only boost about higher power hp/torque numbers but in actual world not much people can fully utilize also.
