Give it another week; you'll find out that your car stinks... 
There are over 100 different additives to our e-liquids, that manufacturers choose from, to make a flavor. VG by itself is not a great carrying agent for these additives, but PG does a much better job. Adding water does nothing, but change the viscosity. The issue we have, is that some of these additives:
-don't carry/blend well, even in PG.
-don't blend easily, so stay "clumped" in the base (base= PG/VG). Fixed by heating.
-are volatile.
-can caramelize at varying temperatures.
-can burn at typical temperatures.
Right now, I'm trying some PGA (just a few drops) in some basic flavors. It seems to be taking off the harshness/acidity, without changing the flavors.
I need a lab.
