Is a convertible Benz the right car for me?

I am looking at this 2019 Benz C-Class C 300 Cabriolet 4MATIC (~$25k, 43k miles). I think it’s a solid deal.

I’ve always dreamed of having a convertible and I think this would be a good choice for my location which has 4 seasons and a moderate-mild winter.

This car is below my means, I’ve gotten preapprovals up to $66k and I technically have the money. But I’m a very practical and frugal person and very keen on wealth building. I’m concerned about the maintenance.

Curious what people’s experience with maintenance has been for these type of luxury used vehicles. Has it been a nightmare or crazy costly? Do you regret it?
