Previous-generation drivers can be strong values because performance often depreciates more slowly than retail price.
Why older models can work
When a new generation launches, a prior model may move into clearance or a deeper used market. GVL does not apply an age penalty. If performance remains strong and price falls, value can improve.
Why years need normalization
Raw review scores from different years are not automatically interchangeable because test fields change. GVL uses carryover models as bridges between years and conservative normalization rather than assuming every year's raw score means exactly the same thing.
When newer is worth more
Paying more can make sense when the newer model provides meaningfully better performance, a better fit, a new warranty or configurations that are difficult to find used.
When older wins on value
Previous-generation models are strongest candidates when performance remains near the top and the used or clearance market is broad enough that the price is repeatable rather than a one-off bargain.
