Be aware that structure is everything. No model between certain dates would be easier to restore that another, but some won't need road tax. Auto restoration isn't something you can just learn, it takes years of experience and practice, it's a real craft so don't expect to spray anything straight away or weld <img src="http://www.zclub.net/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

Also be aware that replacement body panels are either rare if not impossible to find or generally expensive. As the good man once said structure is everything <img src="http://www.zclub.net/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

Never rush something or do it on the cheap if you want to do a quality restoration, if you say well my restoration budget is x and its gotta be on the road in 6 months it's probably not the best idea as this is how projects go wrong. If its gonna be your main form of transport make sure you like walking <img src="http://www.zclub.net/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='

Other than that it can be very rewarding, the book I reviewed restoration from the ground up is a good read, probably best you read it before you buy a Z to get a better feel for things, haynes car bodywork repair manual by lindsay porter is ok, gives you the idea of pretty much everything, but a lot requires expensive equipment or a real skill that has to be taught to you so you won't be able to rely just on that.
Well anyway that's my 2p, have fun, post pics and if you get a 240z before me I will be very envious <img src="http://www.zclub.net/iB_html/non-cgi/emoticons/tounge.gif" border="0" valign="absmiddle" alt='
