exactly... (I tagged along)My dad test drove new cars every year and a '65 Marlin was one of them. At the time the fastback design was a pretty cool deal until the '66 Charger came along. It raised the bar a little(very little). I got to ride along in a 383/ 4bbl version and hoped he would buy it, he didn't. Instead he bought a '66 390 Fairlane GT which was kept 4 or 5 months until 2.. his and hers '66 Dodge Monaco's 500 took it's place. That lasted long enough for a '68 Coronet R/T and a Charger R/T as replacements. The last 2 AMCs my dad drove(and owned) before his death were a '69 390 AMX and a '72 304 Javelin

Car magazines claimed that a 401 GremlinX was the fastest production car of the day.. supposedly ran 12s stock.
