Indy HO cars have been priced at the highest end of the scale. It has opened the door to some cars on the market that aren’t in good shape. Quality currently is not a priority for sellers right now. There’s a lot of cars priced in the $40 to $50 range with broken wings and cracked tires.
The better investment is to purchase Indy cars new. When a new car is between $26 and $30 it’s hard to justify spending more on a used one. There’s no upfront maintenance cost for new cars.
Always consider the cost of the car + shipping and any type of maintenance that it will require. If you have to buy new tires, brushes or guards include this in deciding whether or not to purchase the car. It’s easy to quickly rack up costs since the parts for the cars aren’t typically really expensive. When an HO car starts to reach $100 it’s important to decide whether it’s cost beneficial.
