Leftover Vanity Plates Of The Month

On a Lexus (as usual):  WUT I DO.  Here's what you did.  You bought an expensive care and them put a dumb vanity plate on it.

SKY VIN.  The first part I get, but the second part?  Something about wine?

SUMMRP. A sum of some sort? Or urination in the hot months?

JVSRT.  This means nothing to me, but I just figured I'd put up one of these.  There are actually plenty like this--personal, unknowable, but put out there for all the world to see.
