So you joined just to say that?
Can you imagine cruising a forum that you're not a member of and being like I've got to sign up to say something off the wall!?
To the OP, I agree with some of the above posts. You can probably find a cheap set of stock wheels on CL or FB, maybe even someone that will trade. Stock flares are cheap, used or repros. And then a cheap detail, or do it yourself if you have the time and tools. Clean carpet, degrease the engine, put that black restore stuff on the black plastics, make it smell nice, and that will go a long way. If you don't swap the wheels, buy some polish and get them looking shiny.
Lastly, when it comes to the work you did and the issues it has, talk about it. Talk up the fact that it's got new XYZ. With the RMS, they all have it, and while it's not cheap in a shop, you can use the point that it's a cheap part and can be done with a little work at home. Tell them there's lots of videos and how-to's online. Heck, you might even buy a couple seals and give them with the purchase.
I think the Apex seats for some will be a love them or hate them so that could turn some away. But I could see $10k+ out of that where I'm at.
