It’s a nice wheel, but a little on the heavy side - I know you said that’s not a big concern for you, but I think it should be. They’re not lead weights, but they will probably negatively change the feel of the car, and I’ve had heavy wheels in the past and hated them for that reason. $700 is a lot of money, especially given their age and the fact that one has curb rash. They’re worth what someone is willing to pay for them, but you may want to lowball the seller to see if you can get a better deal. Lastly, the +30 offset fits our cars, but pokes out a little bit in the front - I run a similarly sized RAYS Gramlights 57Xtreme 18" x 8.5" +42 wheel, so a +30 wheel doesn’t have the look I’m looking for. Here’s a link to the wheels you’re looking at on our cars - you’ve probably seen them, but if not this may be helpful:

Either way, have fun and good luck!
