If you're willing to Transport your Car to So. Ca I would highly recommend reaching out to Todd Abrams of A&C Performance 951-696-0500.
He's the REAL DEAL & can arrange his contact to safely pick-up & return your Viper.
I've dealt with a similar situation with a cashiers check for means of payment. I held the title and released the car until funds cleared.
if the arrangement goes bad, report the vehicle stolen to the authorities.
Those who don't know the history behind this car, Josh AKA Warfang was a GREAT guy! We exchanged Viper stories back in the day as he too was a Ca. VCA member.
I hope this GTS lands in the caring hands of another respectful VCA member who will take amazing care of it just like the current...
