a stolen car=a car which was stolen from someone  else =一辆偷来的小汽车

a stolen car（强调状态，失去原来动词所表示动作含义，已经转化为一个分词形容词）

a car stolen (强调动作, 含有很强的动作含义，仍然具有原来动词所表示动作含义）

类似下面2个句子：

(1)The broken vase on the ground is very expensive

(2)The vase broken by Tom is very expensive.

第1个句子强调状态，第2个强调动作。

They broke free and made off in a stolen car. 他们挣脱后开着一辆偷来的车逃之夭夭。

A girl was killed yesterday in a crash involving a stolen car. 昨天有一女孩在一桩涉及窃车的撞车事故中丧生。

The bank robbers used a stolen car to get away. 抢劫银行的人坐一辆偷来的汽车逃跑了.

单个过去分词作定语一般放在前面，有时为了强调动作含义也放在后面，但是有些过去分词作前置定语和后置定语有区别：

an adopted child 收养的孩子

a plan adopted 被采纳的方案
