Oh yeah I've researched them a bit over the years. I know of one not far from me that sells them regularly. But a few I found were fairly cheap and of course due to these issues.
But other cars I've owned had similar issues (or they were prone to) as well. Problem up here is finding ones that are still in good shape body wise.
Even ones from southern US if driven here in 3 seasons (and during rain) can also start having issues over time...without proper protection.
911's etc have become crazy priced as now the 914 is rising in sales...good for you not so good if you want to find one
