So my GF and I spent the last 2 weeks driving from Montreal to Victoria, BC, and then down to Seattle and back to Montreal. It's over 5200 km's each way, not counting the driving we did in each city, etc. We did this in my 91 525, which had 364 000 km's at the start of the trip, loaded with camping gear, without a single problem (other than some brake vibration now from the worn out discs). Truly a testament to build quality when I can take a well maintained 16 year old car on such a long road trip. We even crossed the Rockies twice!
