Some of our parts are no longer available, so we have to recondition old parts which is why we ask for a surcharge when you buy one of our reconditioned/exchange units.
We issue a surcharge for you to return your old unit to us so your old unit can reconditioned and re-sold to keep the cycle going. As the vehicles are 30+ years old if we didn’t do this there would be no parts available for you to buy.
