Automotive terminology is kind of tricky and I'm finding it hard to find good references - although I'm seeing more demand. Here are a couple of links not to forget.
Second topic: I really want to mine the SAP help site for accounting terminology. Here's just a teaser link that's been open on my browser for a couple of weeks now - the technique is simple. Google "site:help.sap.com xxx" for a likely term, then replace the language in the link with "en". Then align your results. It works! A list of likely terms (from a tagger, perhaps) is the right place to start.
A generalized terminology research framework would be useful.
