Those 164's were pretty unique when they came out in the 80's and they got great reviews. Being Alfa's I have no idea how you will be able to maintain them today. I tried to restore a Rover P6 which is another mark that pulled out of the US. I had to buy everything for overseas. It was an expensive lesson.

I do remember that the platform was shared with the Lancia Thema, Fiat Croma and Saab 9000.
