As a companion post to "my top flew off" I have another question: The top rattled quite a bit when driving through Toronto's exceptionally maintained roads (say, like Detroit). Is this common loose body flex or an indication that there is something else at issue? The car already has a strut tube across the rear struts, which I assume was installed to deal withbody flex. Is the rattling common? I moved "up" from my '90 Miata to the newer '96 VTEC Del Sol but find that the slickness of the Miata gearbox is just not there. Do I live with it or are there any "fixes" for that?
