In all my eBay surfing, I’ve seen some funky auctions– buy one get one free, buy one and you need to submit a core (or trade-in) but I’ve never seen someone offer two cars for one price, where the winner selects one car to take home. Why not create two different auctions? Seems a strange way to sell your classic Russian sedan, but in Soviet Russia, eBay auction you! Find a 1980 VAZ-2103 or 1981 VAZ-2106 offered for $9,000 buy-it-now or best offer via ebay, located in Hialeah, FL with a few days to go.
Still trying to get my head around a buy-it-now auction with your choice of vehicle, but $9k is a strong asking price for either one of the Fiat 124 based AutoVAZ built classics you see on the screen. The seller calls the cars Lada-2103/2106, but according to various interweb sources those are the VAZ designations for Russia and for export markets it would have been called a Lada 1500 and 1600 respectively. Engines in either car will be a 80ish horsepower inline-4 mated to a 4-speed manual gearbox.
