Kia Carens II
Super reliable car, very cheap to run. As for looks, for a car currently worth around PLN 7,000, it's not bad, and the interior looks quite pleasant. Apparently, the 1.8 is the most reliable unit - a Japanese engine under license from Mazda. Personally, I drove 150,000 km on LPG. Regarding the engine, I replaced the timing belt twice (every 100,000 km, total cost PLN 400), 3 sets of spark plugs (PLN 37 total), 1 set of high-voltage cables (PLN 45), 1 valve cover gasket (PLN 70, can be bought even cheaper).
