Is the overall maintenance cost (aside from tires) on a stock Supra much higher than an average Toyota?

Approximately how much (on average) do you spend on maintenance and repairs/labor for your Supra per month or every 3 months (not including tires)? Thinking about buying one but want to see how much I would be spending on maintenance first. Also, mention the year and mileage as well, and if it’s the 2.0 or 3.0.

Im not sure if it makes a difference, but if it’s stock or not, mention that as well please.
