My Barracuda was my Grandparents daily driver (they only had one car) and from 1966 to 1985 they put 145,000 (about 7600 a year)
I get the Barracuda in 85 and drive upwards of 30,000 a year for 6 years. School was 30 mile round trip, work 70 mile round trip. Frequent after work Vegas runs (600 mile round trip), It is SoCal and I like to drive. I still look at my Barracuda as a fair weather driver and drive it just about everyday.
The CHP car was retired at about 75,000 and was at about 65,000 when I got it. Knowing it sat for 30 years and the knowing the family that I got it from I can honestly say it is 165,000. I have probably put 5,000 since the restoration.
Both cars do not have their original speedometers and I didn't take time to reset them to zero or match the previous one. On the Polara I made note of the miles on both at the time of the swap.
