If one wants to preserve the longevity of the use of the original, because a direct replacement is not available as a easily acquired New Model or the Producer does not overhaul the Cart' to Original Spec', then the idea of limited usage will have a appeal.
Lyra, during posts on this forum, have made it known, they have certain Cart's offered, that will always be overhauled to Original Build Spec'
If a Cart' is overhauled to an 'equivalent model', with a similar performance, either carried out by the OEM or a Third Party Service, and the Cart' user has no concerns for this variant of the Original Spec'.
The Cart' should not be met with any concern for being used regularly, with the knowing it can be continually used as a result of a overhaul when required.
This is a good method to incrementally reduce the cost per replay for a Purchased Cart' over a period of time, i.e, a Cart' retailing at $2500, is approx' £2.50 per replay based on a 1000 hours usage life. A full overhaul at approx' $500, will produce a Cart' offering 2000 hours usage at $3000, equating to approx' $1.50 per replay. Carry out the same activity on a second occasion and the Cart' cost per replay is now down to budget Cart' territory, where a Cart' from this price range may be discarded after it usage life has expired.
It is common to see reports of 1500 - 2000 hours usage life in a Cart', if Cart's known for this longevity are considered, the above equation becomes even more attractive, if a Cart's cost is a concerning factor and deters a buyer from purchasing.
