rare Buick

I have a 37 Buick 4 door sedan with trunk.  I always check to see what other similar cars are selling for and try to get an idea of how many there are out there.  Tonight I came across this 38 - pretty well the same car except the 38 had coil spring rear where the 37 has parallel
 leaf rear.  I like the grille on the 37 better as well - I need a good one if you know where there is one.  If you follow my writing you will know I dream of owning sets of similar cars and a 38 to add to my 37 would be cool.  I could restore one and street rod  the other.
