HYPOTHETICAL: Buy three 1-1.5M cars over 15 years (replace and buy one every 5 years) or buy one toyota landcruiser lc200 now and keep it for 15 years?

Like for example, i buy a brand new 2015 mu-x now then after 5 years i sell it to get a brand new 2020 fortuner or the like. Then after 5 years i sell the fortuner to get a 2025 forester.

Or is it also of sound logic that i get a brand new 2015 lc200 now then keep it for fifteen years?

Will it still have a "dating" 10 years from now than a brandnew 1.5m car? Will it still command more respect than a 2025-2030 fortuner/forester/ms/tb and the likes?

Circumstances:

Personal car. Daily driven(asphalt hi-way). Small family.
