This is personal opinion only but I think the Cadillac is best left as is, maybe with something simple like real rider swap. Great job and very fitting color choice still.
For me, that’d be the Cadillac DTS from 2006 to 2011. Diecast makers did their work on the older Deville, the CTS series, even the concept cars. but still, I can’t see them giving us the DTS any time soon
