We bought this 2000 model Mercedes-Benz C200T for $3,400. It had travelled around 220,000km. It's white with 5-speed automatic transmission and black leather interior, including built-in child booster seats which my son likes.
It's been quite reliable so far. The only issues were the battery needed replacing and also the front steering rod.
Unfortunately it's got a little bit of rust and the transmission is slow to shift from 2-3 uphill.
