The car was driving fine when I bought it with 305.062 km (!) on the counter. The previous owner had obviously reached his target. Still one could see the rear wheels where not positioned vertically straight, and this often means the rear arm bearings need replacement. After fixing, the car drives even better.
It's my second 305 break gr. I had a little accident with the first and I had to sell it. I just couldn't resist buying the second one for only 240 euro... Repairs by garage cost 600 euro, so in total it's quite affordable. Repairing it yourself will cost about half, but you'll need some special tools to compress the rear springs in order to replace the bearings.
I'm still amazed by the driving quality of the 305 break. It's so comfortable and steers very good. It's real fun to drive! Take the chance if you get it! Loading space is pretty big and the engine has plenty of power too. The building quality and reliability of the car must be great; the motor doesn't have any starting problems and just performs healthy even after this amount of km, and there's very little rust.
One minus; the brakes are not that great, both the 305 breaks felt the same. The brakes are working, but a 205 for instance simply brakes better.
Above all, the 305 Break looks beautiful, I like the design a lot, and my break is in such a good condition that I carefully try to avoid another little accident...
