I like 7 as well, but 6 is kool too. I once found a distributor for the #7, but I emailed them said lets do this, and they were gone so its actually good I didnt act sooner, probably woulda got shafted, they were in lithuania, autonoksa.lt, cheap too only like $350 USD i think. And erebuni used to have them, now i dunno... If you or anybody finds out, post up, they're pretty kool. Otherwise, it looks like it'll be a custom job from a body shop. Probably not even all that complex but probably cost a bunch.
BTW, I think the CE corners and stops just dandy, no "need" to upgrade. Especially around town and stuff, the ride is "sporty" enough.
