Disagree.
A built Cruiser is likely to have been taken care of. Knuckle job, good brakes, engine leaks gone and much more. Not to mention all the money you can save on buying upgrades if they are already on a Cruiser. Seat will probably be fixed, carpet replaced and much more.
You buy a stocker that has been a bunch of peoples daily driver, kids and dogs raised in it, you best expect $10+k to baseline it. Interior may also be disgusting.
I always say judge the Cruiser. There are examples of stockers in good shape that have only changed hands a few times. There are also built Cruisers that are trashed.
A buyer should always educate themselves before purchasing. Best to inspect in person, yourself. The folks that don’t do this or don’t get a 3rd party PPI are most often the ones who end up with a mess of a Cruiser.
