How many cars will you buy in a lifetime? My acquisition of cars has basically been buying the "hand me downs" from my Dad (the car guy). I started driving an old 1972 Buick LeSabre, and when I look at chain of cars I would be considered brand loyal to GM.
I have also indirectly purchased cars for Susan and Jenna (so I count those as a "side chain").
Because cars are usually the second largest consumer purchase (behind the house) they become milestones or place markers in the timeline of ones life.
My Personal Car History:
1969 Buick LeSabre - Driven a Miami 1976
1976 Buick Century - Delivered to Cincinnati by my Grandfather 1977
1978 Buick Regal - Purchased from Scott Buick for $5K cash
1986 1/2 Toyota Supra - Purchased for $19K Kept until 2007 - The guy sports car thing!
1992 Cadillac Deville - Acquired in 1996
2002 Cadillac Deville - Acquired 11/30/2004
2006 Cadillac DTS - Acquired in 11/15/2007
The side chains include Volvo, GMC, Ford Explorer, Honda Odyssey, Cadillac Escalade, Chevrolet Equinox, Ford Freestyle and now Tahoe.
So my personal numbers - 7 cars over a driving history of about 30 years (4.3 years average per car). Cost increase from $5K to $50K.
Like father like son - my dad's chain 26 cars from 1940 to 2010.
