1960 avg vehicle survived 92kmiles before scrapping
1970 - 105k
1980 - 132k
1990 - 191k

1970 15 percent of vehicles 10 yrs or older
today close to 40 percent are 10 years or older

1980s 20 percent of 5 to 7 year old vehicles scrapped
today only 10 percent of 12 to 13 year old vehicles are scrapped

dealers service the majority of vehicles to age 5

ten years ago a thousand dollar bill for a ten year old car sent it to
the scrapper because it had reached its lifespan anyway.
today that car is probably fixed and expected to last another 5 years
