Orderd a new 2020 Oxford white f250 with tremor package two months ago. It will take something like 9 months to get license plates for it. Already got the VIN, but was not produced yet. That was three weeks ago.
Where would we be without a cell phone. In the old days if I had a problem with my machine I had to drive a large distance to a phone booth to call a mechanic. He than said try this and that and than call me back. It could last more than a day before a minor issue was solved.
