Evan I have seen a number of second hand spec racers come through for a very good price. Check over at the FF5 forum. As for turning wrenches, I used to turn wrenches partially in exchange for some seat time. Perhaps you could find some one with a similar desire?
How about a Coupe?
I am with you on shows. I don't do 'shows' but I will do cruise in's. First of all, I don't have a show car, secondly the cruise in's (I suppose some of them you could call shows) is more of an excuse to hang out with buddies than anything else. I would love to do some track time but that would mean some changes I don't know if I want to make. Plus of course, time. I do Solo II which you might enjoy. Just be prepared to have you a$$ handed to you by some kid with a Civic and a fart can!
The Noble has been getting rave reviews and there is a waiting list so who knows, it may pan out to be a good purchase. By the way, I don't know how old your kids are but when was the last time you tried and squeze you hind end in the back of a 911? Last time I tried it wasn't pretty. Hell the seat wasn't even big enough to take a baby seat! That is why I think all vehicle with more than two seats are a waste of space!
