We had extremely good timing buying our new minivan last year, 100% due to pure luck with when our previous car crapped out. We used the Costco buying program, which basically let us go in knowing what we would pay with a pre negotiated price and not have to haggle, and shopped in early April. We were looking for some specific trim options and the dealer let us know that they were out of a few of them due to shortages of some chips, but they did have a whole bunch of a different trim level. We walked out happy with a new van just a few weeks before inventory levels tanked and prices started skyrocketing.
