If it burns oil, yes. If it needs a head gasket, probably. If it needs a brake booster, your call. All depends on your finances, a new or recent car will be more reliable and have less $2,500 to $7,500 repairs in its future. Plus better crash test ratings and far better safety systems.
if it is running well with no issues, sell it while you can before a big dollar breakdown presents itself. it will bring good money if it has no issues
