I've seen exactly 4 actual LCAR models in practice this year... ATS, XTS, MKZ, and Audi A3. GXAR is what makes an LCAR res such a big question mark to me... everything from Q50s to SRXs and MKTs, none of which are all that well appointed in a meaningful way (NAV being my main criteria). So LCAR and PCAR have pretty much equal variability, while the actual PCAR class seems to be reeling that in and LCAR seems to be adding more flashy/expensive models in bare-bones trim.
