While I agree to some extent, it is not just a matter of time to change the perception, but also a matter of more vehicles like the MKT and MKS which share a platform, but look essentially nothing like their counterparts. The ES330 has not been made for years. The ES350 does not share any sheetmetal with the Camry. The MKZ, while better in this go around, still shares too much sheetmetal with the Fusion.
Infinity does not make cars.
