Doesn't seem like you have many choices with your price and mid 12 sec requirements. I have no idea what the 1/4 miles times are on these or what they go for used, however off the top of my head they may be in the ballpark.
- Camaro SS or ZL1
- Mustang GT or Shelby
- CTSV/ATSV
- Corvette C6 Z06 or none Z06 C7
Or accept defeat get a used Model 3 dual motor or performance and bow to master Elon.
