All the plates from the OP (except for #6) have been guessed.
MEXFOOD = Fiesta
DA GAMA or MAGELLN or CORTEZ or STANLEY = Explorer
WLDPONY = Mustang
DINOMIT = Nitro (although Jenaroph had a great alternative)
LOUDLY = Forte
SCAMP = Rogue
LMNT 27 = Cobalt
palindromemordnilap, remember, vanity plates are limited to 7 characters, so the “HIDDEN AG” gets tossed. Although, you get beaucoup points for the “Red Taurus”.
I especially like the riffs on 357 … golf claps go to tumbleddown and Telemark.
needscoffee, your “Pinto” answer for DINOMIT marks you as one sick puppy, but it made me snicker, so you know where that puts me.
In passing, I actually saw the SNAAB one back in California about 20 years ago.
