Need technical assistance

Hello, I’m facing a problem, I’ve got 2Kids (5months+11J.) and I’ve got to get out of choice…use another car. My current vehicle, an old 16-year-old toyota Starlet, is slowly giving up my mind. Loses water and stinks when I leave out the heater. Would like to do something bigger now …. My financial resources, however, are limited and therefore can’t afford to buy anything wrong. Now the following 3 cars are available… Alfa Romeo 155 Data: 172,500 k m, 93 kW (126 hp), EZ: 10/94, TÜV: 08/05, AU: 08/05, grey-metallic, 4/5 doors, petrol, special features: ABS, central locking, leather equipment, light metal rims, sliding roof, electric window lifter EUR 1,100 or a VW Jetta 1,8 data: 176,000 km, 66 kW (90 hp), EZ: 06/91, TÜV: 01/06, blue-metallic, 4/5 doors, petrol Special features: light metal rims, sliding roof EUR 1,200 or a Citroen XANTIA 1.8 data: 145,000 km, 74 kW (101 hp), EZ: 02/94, TÜV: 05/05, AU: 05/05, no colour indication, 4/5 doors, petrol, special features: ABS, central locking, el. immobilizer, electric window lifter EUR 1,250 More I can not spend….
