Edit: After consideration, I’ve changed a couple of my guesses.
#1: Lotus 3-Eleven #2: Holden FX Sedan #3: Jensen Interceptor #4: Toyota T100 Baja Truck #5: Chevy Vega. Vega as in the star, Vega as in the problematic Chevy. #6: AMC Gremlin X #7: Mitsubishi Starion ESI-R
Some Tricky clues, but i bet this one solution as the guess for clue n°1.
“You’ve got to trust your instinct” it’s a reference for a song, by 311, called All Mixed up with Lyrics…
311 it’s the number of exemplars produced of… the 2017 Lotus 3-Eleven! also (311= 3-Eleven)
Clue number Five it’s the 1971 Chevrolet Vega GT! Vega it’s the most brightest star of the Lyra constellation and even it’s a bad car for Chevy himself… it’s stll a star because her name
Clue number Six… it’s a shoot in the dark for me, but maybe it’s the 1973 AMC Gremlin X? Gizmo it’s the main creepy monster in the famous horror movie Gremlins.
I hope you’re right. Because if they just used 311 as a clue I’m gonna lose it. Makes sense with them being over on the West Coast, with their appreciation for songs to get uh.. you know.
