Indeed, i was lucky i got to order back in jan 2020 (pre covid) for april handover but the 1st lockdown stopped me getting the car until mid june, it was at the dealers all that time and i did have a test drive prior to ordering. I deffo would not order a car without at least test driving it and sitting in the seats that i would be getting, because not always is the car you do test drive is in the trim you will be getting, often it’s different.
The other thing is i dunno how mb can hold one to blame if it is not suitable, if you can order but they know that you cannot test it out fully and it’s just not right for you once you get your hands on it..
Also dealers are taking orders in some cases, then it’s sorry it will be x date then another date etc etc and then it’s 9 months later and still no new car.. Crazy really but as i said mb must take some of that blame imo as surely they know the situation and are allowing ppl to order knowing full well the declaration one signs is now not worth the paper it’s printed on.
