I didnt own an estate but I
I didnt own an estate but I owned a 1999 Peugeot 306 1.9D-turbo. Great car, really easy to drive with very pleasing mpg. I know the estates have a good size boot, friends can fit 3 or 4 bikes inside with 3 on the back comfortably.
Mine could also tow a 6m, 80hp rigid inflatable boat if that gives you any sense of torque and grip.
Also, given that these are common cars they are very easy to find parts for and to fix yourself.
I found that a common issue with 306’s was a knocking from the front wheel bearings and suspension struts. Its simply a case of keeping an eye on it and noticing any dodgy noises and pull on the steering. The other things to look out for are the same as on all diesel cars, nothing specific to peugeots in my experience anyway.
