This is a 1951 Buick two-door built by 2 Lane Blacktop from Reklaw, Texas. The car runs a Fat Man front subframe, Ridetech Shockwave air suspension, Ford 9″ rear end, and of course a Viper V10.

I would like to buy this car if available by current owner.
The only way I could think to get in contact with the owner is get in touch with the builders. But their company seems to be out of business.
