Upgrade 986 or buy 987?

[dascar]

In the spring, I plan on either selling my 02 Boxster S (Speed Yellow, 33k miles) and getting an 07-08 987 Boxster S (Speed Yellow, of course - budget of around $26k) OR spend $6k in upgrades on my car such as new turbo front bumper, side valances and perhaps an exhaust mod. What do you guys think? Is newer better? More HP, real glass window vs. plastic, a tad more interior room plus all new dashboard, sexier body and it already has the cool front bumper with big air intakes as well as non-fried egg headlights. However, I could save myself $5k or so by keeping my car and have a pretty unique 986.
