Any time! Some people hate it, but I love going to dealerships, the trick is knowing when and where to say something, not so much what you say. Until you've signed you can do almost anything, short of assault or outright cussing them out. Dumb dumb was about to tell them how much money he had, I had to step on his foot to stop him. Sit near the showroom don't go to an office, plant yourself there, so when you get boisterous you'll start annoying and scaring the other customers. I actually yelled almost complete gibberish yesterday, to see what would happen, and they barely noticed. The sales people will have something else to worry about, then. I love it, gets the juices flowing.
You're not going to be terribly happy with the Daytona then when you finally get one. Mythos would have us believe that the GTO could go head to head with a current GTP car and eat it for breakfast. The truth is it was competitive for it's day. Like most classics there are generations of technology between them and current offerings. Spend some time in the seat of another car from its era and then jump back in. Your perspective will change .
Local fellow picked up a boxster in the States for 11K. Needs detailing but mechanically in surprisingly good shape. They are the bargain basement sports car right now when you look at what competes in the price range they occupy. You do have to be conscious of the maintenance costs but it's hard to turn away from that car at the prices they are fetching.
I like driving the Daytona (I have a coupe), but they're GTs, not race cars or even sports cars. The GTO is fine, it is what it's supposed to be, but the hype around them is as thick as Mississippi mud. We are going to put larger brakes and stronger springs on it, that will help.
