By the end of my time with it, my 307 headlight stick would also trigger the horn whenever I turned on the high beams, the AC would stop working at around 90 KM/h, the air intake pipe to the turbo had at least two tears glued down and I had to carry a 5L jug of water replenish the radiator on hot days. I sold it with 340k KM and AFAIK it's still being driven, refusing to die.
I had a jury rigged wiring harness for the front indicator lights. The exhaust consisted more and more of my crappy stick welds rather than original metal. I had changed basically all suspension and brake parts at least once myself. Main headlights were starting to wear thin since the haze had been polished off many times.
Drove it until the front right wheel literally fell off during one Christmas holiday (the steering link broke and the wheel turned 90 degrees out, fortunately at low speed). At that point it had close to 300 000 km on it, and we had been test driving new cars for almost a year in anticipation of the final trip to the eternal rusting fields. Total cost of ownership was amazing though, and it was really spacious and practical, I miss that car.
