Stumbled upon this forum several months ago when first considering upgrading to either the LC or LX (or GX). After months of looking, I've narrowed it down to a low mileage '16 LC versus a similarly low mileage '18 LC. A few thousand dollars different, but same CPO warranty. Aside from losing 2 years on the warranty, are there are noticeable differences? I've read some threads about a change in radiator design, etc. but can't find anything that (so far) causes me concern. Thanks in advance, looking forward to it.
