Sabre GT in Yellow with Black Stripes or Black with White Stripes. I went on my Original GTA 4 save a little while back from my first run through, and literally every safe house has two Sabres outside, all with different paint jobs.

The Sabres were my favorite. I loved them in SA. I would always paint them black, tint the windows and put some of the beefiest tires they had. I filled my garages with them and whenever I was going out to just wreck **** and kill people, I would hop in one of those babies and feel like a bad ass killer.
My second favorite car was the Mafia Sentinal from GTA3. That thing was just awesome and when you could keep the one you got on one of the missions that was bulletproof just made it even better.
