Crash safety has become grossly exagerrated because the standards have been sharply rising last few years. Most 15yo cars will keep you safe just fine in a median crash.
A 15 year old car currently is going for 5 figures - not a shitbox. Not unless it’s a shelll of rust held together by bondo. Then your crash standards or whatever year are meaningless as the chassis may have 25% or less of its design strength.
