Lower spec engine, only 2wd, totally different car in my opinion and I’d tell them to take a flying f***.
No way would I pay nearly 10 grand plus advance payment plus extras for a car I didn’t want and especially one that won’t perform the job you need it for (4wd in bad weather etc).
A full refund and full written explanation is the least I’d accept.
Dealers are just taking the piss with mota customers more and more, one of the reasons I left the scheme a few months ago.
