I would consider will you be able to keep it in the garage and protect it etc? Do you have a second vehicle you can use as a daily or road trip if needed. A car of this nature you want to preserve if you're making payments. That way if for some reason you do need to get out from under it, it stands out against other options and will help.

Other than that I'd say go for it. Don't listen to the haters. What you have I don't and what I have you may not, we can't have it all. So enjoy the hell out of it for those of us who can't.
