I've never seen this with a bicycle, it takes a lot of money to buy tires, liners, slime sealant, parts and accessories (lights, horns, tanks, baskets, racks) and occasionally rims and truing...
The scale of maintaining a bike is almost on par with that of keeping up a car. Once you get to a certain point however and treat it right, either one will have stable operating costs, other than fuel in the case of the car. You have to keep both serviced regularly to achieve that and there are no guarantees.
And I have six bikes, No. 7 is actually for a relative when it's done. I've owned at least two dozen bikes in my life.
