My brother has a '92 Duster (mine previously), 3.0, 5 spd
'91 Daytona , 3.0, 5 spd
'94 Shadow, 3.0, 5 spd.
They are fun cars to drive.
There was a '93 Shadow in the junkyard, recently. Convertible. It was really nice. A relative of the deceased owner drove it to junkyard. 'didn't want to fool with advertising and haggling', she said.
