Depends on condition.
When we bought our 2002 Volvo V70XC - it had 92,000 miles, unknown oil changes, but there were stamps in the book. It’s always used a bit of oil, but despite that unknown, it soldiers on with 308,000 miles on it, still using just a bit.
The 2002 V70 T5 - had no stamps in the book, had 75,000 on it, and has never burned a drop of oil. It is running perfectly with 230,000 or so.
Both cars were in great condition.
I can fix mechanical. I don’t care for body/interior work.
That said - I am leaning towards new as the results of a couple of factors:
1. Parts support dries up after 10 years, and by 20 years, is very poor, particularly for trim, body, and interior pieces.
2. I have less of an appetite for doing car repairs on the daily drivers.
3. The crazy used car prices recently have negated the cost savings of buying a 3-5 year old car.
