What are the peaks at 2005 and 2007?
The peak for 2002 was an engine.
What's the red line? What's the green line?
Sorry the legend got truncated in original post. Green line is annual miles driven on secondary y axis. Orange line is average odometer reading (divided by 10) and also on the secondary y axis.
2005 - $1100 repair at overpriced shop (now out of business) to replace water pump and intake manifold gasket on 2000 Chevrolet Venture.
2007 - ball joints, wheel bearings, water pump on various vehicles.
Numbers in recent years are skewed because I've bought older vehicles for teenage drivers that required lots of little things to make them roadworthy. And then they got wrecked and I had to fix up replacement vehicles.
