Brian, glad to see the car get a good home.
As far as parking 3 cars in the 2.5 car garage I would put the K-Car sideways along the back wall and then park the Omni's side by side, should leave you with better access that way. The first year I had my place two GLH's, my Ram pickup and the lawn tractor with a snow blower on it all fit inside my 2.5 car garage
