Cool!
Here's the window sticker from my second Spider, an '86 Graduate with no options. $14,470.
Was Manhattan Motors the Alfa dealer in Rockville in '86, too? My first '86 was sold new in Rockville, according to Alfa's historic records in Arese, but I don't know the name of the dealer. I assume it was the same. Somewhere around here I have a dealer list from '88 or '89, but not one for '86. For what it's worth, I bought the car in '05 in Bethesda, Maryland, just inches from Rockville!
