I would be curious to know what the average length/time a current consumer keeps their vehicle before trading/selling for a newer vehicle...I'm betting it's a lot less then the old days. .
for me as follows...
2000 audi A6 2.7t = 8 years 110,000 miles
2007 Volovo S60r = 7 years 100,000 miles
2013 SHO = 2 years 35,000 miles
2014 Explorer Sport = 6 years 100,000 miles
2015 Mustang Gt = 2 years 35,000 miles
2015 Audi SQ5 = 3 years 50,000 miles
When I like a car, 7 years and 100,000 miles is my target.
