The problem with some older cars is that they can't stand to a leaner burn without the risk of melting their pistons due to the absence of oil spraying nozzles, having to rely on a richer air/fuel ratio for cooling. But anyway, an eventual retrofit into an old iron to improve its emissions and fuel-efficiency is still most likely to be less energy-intensive than building a newer econobox which would be supposed to take its entire expected life cycle to overcome this initial disadvantage.
