What Is This Car Worth?

[LightngSVT]

OK the title's a little misleading as I have a few cars Im very seriously considering and was wondering what the experts here thought of them. I know they are 987's but you guys seem to be experts.

1. 08 S, 55k miles (seems pretty high), $31890, the miles are a huge issue and I know they've had this car at least 3 months- 2008 Porsche Boxster S - Used Cars For Sale Columbus, OH Prestige Euro Cars

2. 08 base, 44k miles (higher end), **certified!!!**, $32500, Love the 19's not really wanting a red/tan car but its growing on me- 2008 Porsche Boxster Guards Red | Knoxville, Tennessee | Harper's Porsche

3. 06 S, 32k miles, $29995, a bit older than I wanted and silver over gray is a bit boring but its got price and miles on its side- Used 2006 Porsche Boxster S For Sale in Tuscaloosa AL | Birmingham, Bessemer, Hoover | VIN: WP0CB29856U730824

I really think I'd prefer an S but could be happy with a base Im sure.
