high mileage boxsters?

[j.fro]

2000 S with 124,xxx miles. I bought it in Feb '06 with 60,000 on it. I change the oil every 5,000. I've added headers, guttted the cats, and opened up the muffler (the sound is phenomenal!). I also added an EVO intake with AEM dry-flow filter. The struts were replaced with K-sports, and I've got R-comps for AXing. There are a few other mods here and there.
I've AXed the car for 3 seasons, winning the Boxster class with the local PCA, and finishing in the upper third with the SCCA and another local organization. No babying here.
She runs great, doesn't use much oil, and hasn't given me any headaches other than the expected stuff: AOS, CV boots, MAF. Oh yeah, original coolant tank and clutch!
