Speaking of long trips in old cars, recently not back then.
I purchased my first 69 Polara with 4 pictures and a 5 minute phone call.
After flying from Santa Barbara CA to Butte MT I made my way home. The first 250 miles or so the road was covered in snow with a single lane clear and at times all covered. My plan was to take I-15 into SoCal but the further south I went the worse the snow was getting. I almost called it a night in Idaho Falls but was afraid I'd be trapped in the morning so I continued. Pocatello was the first chance i had to turn west with hopes that I'd get away from the mountains and have better weather, it worked.
That drive was 1400 miles 8 hours one day 12 the next.
My longest trim in a vintage car was a road trip in 2009 with my 67 Barracuda.
That trip took me up the California/Oregon coast into Portland returning south through Bend and Crater Lake.
Mount Hood in the background. That trip was a total of about 2200 miles.
In June I may be taking the Polara to Astoria (2000 mile round trip). Even though the gas mileage isn't that great it is still cheaper than a rental car.
I only have old cars and will drive any distance for the right car (for the right price)
