The Justy had a very small 1 liter EF 3 cylinder engine. A 1.2 liter engine was an option. Both were very weak engines, which might explain how the car was able to get such great mileage. There was no automatic transmission option, just manual and CVT (pushbelt). The engine was not strong enough to support an automatic transmission.
The 5 speed manual transmission version of the Justy was very reliable, despite the fact that was very noisy. The transmission was not very smooth and didn't synch very well, but it just seemed to work forever. The CVT model was not nearly as reliable, especially outside of cities, and therefore was not popular in much of the United States.
Despite the small engine, there was a four wheel drive on-demand option on the CVT Justy.
The Subaru Justy was the last carbureted car to be sold new in the United States. It would be canceled after the 1994 model year.
There are still plenty of Justys out there on the used car market in the US. If you would like to buy a used Subaru Justy, or just parts for your already well-used Justy, be sure to check out the listings on eBay for some great deals.
