Is a Used Sports Car Worth the Maintenance Costs?

So, I’ve been eyeing a used sports car for a while now something like a used Mustang GT or maybe even a BMW M3. I love the idea of having a performance machine, but I’ve heard horror stories about maintenance costs. I’m not afraid to get my hands dirty with basic upkeep, but I’m wondering if the bigger repairs and parts replacements are going to drain my wallet.

For those of you who’ve gone down this road, what’s your experience been like? Are there certain models or years that are more reliable than others? Or is it just a given that owning a sports car means budgeting for some hefty repair bills? I’d love to hear your thoughts and any tips you might have for keeping costs manageable while still enjoying the thrill of driving something fun.
