There's no such thing as a Lada full-size sedan. The longest one was something like 4.15m long. Contemporary American "mid-size sedans" were over 5 meters long and even "compact sedans" were quite a bit bigger.
My mistake, I meant the 2106/2107s that were sold in Canada. I am not sure if wagon variants were part of the lineup as well.
I said full-size to mean the “largest” RWD sedan offering to contrast with the 2121, 2108 and variants that were also sold in Canada. Make no mistake these cars were small compared to contemporary offerings.
