Of the last 5 vehicles we have had, 4 have been brand new. We tend to keep them for a long time. 1992 vehicle was 13yrs, 1993 vehicle was 19yrs, 2006 vehicle we still have & just were gifted a 2017 that we plan to keep for at least 20yrs. We were gifted a 1996 used vehicle that we had for 6yrs but it needed so many repairs as it wasn't well maintained before us & wasn't really able to pull our travel trailer anymore.
I do know that vehicles depreciate the moment you drive them, but I think for us, the new cars we have purchased have been pretty good choices, we have maintained them well & they have lasted us a very good length of time. I would buy used vehicles, but sometime you just don't know what you are getting (same with new but usually there is a warranty to fall back on).
