Stop looking at what's available until you are ready!!!!
That's what happened with me and the 928 GTS.
After my 944 Turbo tanked and I sold it, look at regular sites for BoxsterS's and 911 Cabs with PASM just to see what years and how much money I needed to save. While looking pulled up 928s to see what my old 90 928 GT would be worth today and stumbled on a 5 speed 94 928 GTS in Iris Blue Metallic/Classic Grey. A very pretty blue 928 that is also very rare. Not only that it also had all the suspension etc upgrades that I would do and in perfect and well maintained condition. Tried for 2 weeks to talk myself out of it and ended up deciding there would never be another 928 like it come up for sale. Offered the guy much less than he was asking and HE TOOK IT.
This is from the autotrader add. There were only 4 made that color. 2 5 speeds and one was totaled and scrapped. One of the 2 Autos is in Helsinki.
At 46K miles it wasn't enough to be a low mileage collector car, but low enough it's a really nice car.
So...I have to tell everyone to NOT look unless you are willing to buy because you just might find that one car.
