I just found one for sale! Also in Paraguay!

I just saw that the Spider wheels do not fit the Q4 well, it is beautiful in the Supers specially. The car doesn't seem to be in too good condition (looking by its seats), but as there is no 164 Q4 in Brazil, it is certainly a good acquisition... even having to go to Paraguay every 6 months to renew the license to drive it here, it is a good addition to any collection.
Although seeming to be expensive (equivalent to US$3500), for brazilian standards it is really cheap (the average price of the 164 is around US$ 9000, for a good one, 12000, 13000, having reached even 25000). The only problem is that we cannot import it to Brazil until it is 30 years old... but there are some ways to run it here without problems...
Let's see if any member of the Alfa Romeo BR club interests on it... If I had money, it would be coming to my garage right now...
