The SVT's performance is surprisingly good, but the suspension can get a little uncomfortable as a daily. It tracks ruts like crazy on the freeway, and can be slightly jarring on rough roads.
If I were looking for a fun, comfortable daily, I'd go for a late model SE sport manual.
But then again, I bought an SVT, so don't listen to me. Nothing puts a smile on my face quicker than a second threw third WOT pull. By the time you can check the speedo, you're going too fast.
Keep in mind that parts are becoming harder to find, at least in my area. I find myself hearing "no" at the parts stores, "no" at the dealership, and "take it" at the salvage yards. But then again, those are for more uncommon parts.
As far as longevity goes: just passed 150k. No signs of needing major repair since the last major repair, so i guess I get this weekend off.
Zetecs are fun, SVT's are IT.
I've never driven one, but can only assume the SE is in the middle somewhere.
