Hi there,

It is sure that 184K miles sounds alot but a good compression test on the engine will tell you more than anything else about the car. If the engine is in a fairly good condition (i,e: good compression), the rest of the car should be in the same condition, wich means the car has been properly maintained through the years.

Is the engine turbo or non-turbo? To be within the manufacturer specs, the compression should be at least 150 lbs for a turbo and 180 lbs for a non-turbo. Dont crank over than 5 compression strokes. If possible, record all strokes readings and let me know. Note that the compression should build up quickly in a healthy engine. Low compression on the first stroke, followed by gradually increasing pressure on sucessive strokes, indicates worn engine and the rest of the car will be without much doubt, in the same condition.

At least with that info, you will be able to make up your mind on it.

Keep us posted !
