Who here drives an old beater for your main vehicle?

I see guys at work buying new trucks every couple years, have never not had a car note, and they laugh at me for driving a 2005 Dodge Ram 1500 Hemi. It has 137K miles, less than $1500 in repairs (not including routine maintenance).
The Ole Gray Mare just won’t die. I didn’t even buy her new, I got her in 2008 for $15K.
Last week during the freeze, I didn’t have anti-freeze in her. She froze solid. I cranked her up, drove about a mile. All kinds of lights come on (check engine, throttle body). I realize what’s going on, turn around, drive home, pop the radiator cap. It’s a solid block of ice. I put a heater under the hood and buy a new radiator for $150, change it out real quick, no problems.
My biggest maintenance cost in 13 years were new U-joints for $300 (and that’s actually routine maintenance).
I don’t get driving a new truck to a plant, with all the cooling tower fall out, etc.
I will drive it until she’s dead. This is my work truck, and has been more faithful than some of these $50K+ trucks other guys are buying.
