Good thread, enjoyed this one. I'm like...what is an Evo (showing my age I guess) so I looked it up...oh I said one of those twangers the young men drive through my neighborhood while they drool over my porsche. Really not picking on the car, it sounds like fun if you want to track or just like raw a-s power. Again these are two totally different cars, and this stuff about being faster, heck if I drive my 2000 Boxster 'S' anywhere near the RPM I'm being told to, well I can't get out of 3rd gear without the cops chasing me. Me personally I couldn't sleep at night if I put $40k into an Evo, but for you it sounds like something you would really like...you should go for it, if your 03 'S' is nice I'm sure there are plently on this forum that would help you out

. Or if you still love your Boxster get things fixed, save a TON of money and have some peice of mind.
Heck I got my Boxster in early Nov, before I got it I couldn't wait to drive my 09 E350 each day, now I'm thinking of selling it...I always say wait two weeks and see how you feel. My Benz is for driving and the Boxster is for the joy of working on it, though it really doesn't need a thing done, it's just fun and easy.
Post some pics so us plastic window guys can drool over your glass window.
