My 1987 Buick GN ,myself turned GNX,back in 2013.
I've Owned this car since March 1991.
She Shows, She Goes,
She breaks necks inside an outside of the car.
She was built to beat 2010 Bugatti's. (Then the McLaren P1 came out)
She will ProTour or ProStock, Only Tire choice depends.
She's maintenance free, less oil changes an detailing.
