Buy the Evo.
My 15 year old son and I went out a month or so ago and drove a new Evo, and I was really quite impressed with the performance and handling. I felt that it was slightly quicker than both my '91 NSX and my '02 Boxster S, and that the handling was superb. The car I drove had 1800 miles on it, so during the test drive I got to really push it, and thought it was a blast.
I ended up buying a very rare (1 of 16 built) 1987 Porsche Turbo Look Cabriolet since I felt that the Evo would probably depreciate to the low 20's in a year, and that the Porsche wouldn't.
The dealer was willing to sell me any of the 4 cars he had for $29,812, which was MSRP less $1000. They were asking MSRP plus $3000 ($33,812).
