What's the WORST car/truck you've owned?

My company leased 25 Chevy Astro Panel vans in 2008. Of the 25 3 of them needed rear axle replacements at 2K miles, 4 of them the sliding side door came off their tracks and landed in the parking lot(one of them hit an employee's 2004 BMW M3) and half of them the engine lights kept coming on after they went in for service. They all received the same recall and when they returned there was a burning smell accompanied by a buzzing sound from within the cab. Other than that they were great work trucks. And did good burnouts. The V6s in those things were good power wise.
