Hi Mike, and welcome to the forum. $12k for a 23000 mile "Red" roadster sounds like a good deal to me.
Like you, I really don't like working on my car either, (other than changing the oil) but I do love driving it every chance I get. 48000 miles in 5 years, and really not any mechanical problems. Just a vacuum leak in the hatch (repaired under warranty).
I never drive mine in the winter, but there are many here that do.
I can't recommend a Crossfire enough. With 100 cars under my seat belt, about 25 Sports cars, this one has been my favorite.
Go for it, you won't regret it.
