A bit late to the angel eye party: 2001 M5

[Beej]

Car was running a bit cool and the coolant was sort of a nasty brown despite the cooling system being replaced at ~70k and the coolant being flushed more recently than that.

So a thermostat, full coolant flush, and garage floor cleaning later, we're back in business. I also replaced the expansion tank because they're known to fail*.

* just kidding, they never fail, I just can't resist shiny things.

I also ignored PDC and backed this thing into the M3 while juggling cars and cracked up the rear bumper real nice. I'm sure I'll fix it proper at some point but $25 of touch up paint beats a $1200 body shop quote, so I'm just kind of pretending it didn't happen for the time being.
