I know it's not a Z, but a Nissan nonetheless and one could convert to an L-series under the current ruleset if they were so inclined. Anyway, an insane deal, I came very, very close to pulling the trigger on this but passed due to various reasons. The owner started out in the 40's from what I hear and is now down to 20k, including the trailer and all spares - you can't get a spec miata for less than that! Unfortunately he's lacking on the pics (however available upon request) but it's all professionally done, alot of trick stuff on there including a Saenz dog ring box which alone would probably go for about $3k used, here's a vid of a Bimmer with the same box:

You probably won't find a better deal any time soon, here's his Ebay ad:

Good old S chassis, sounds like a great buy but why replace the multilink rear suspension with a Watts setup? Just curious, does not take much to get the multilink working well.

why replace the multilink rear suspension with a Watts setup?

It's a custom build from the ground up using commonly available circle track stuff - for the most part the norm here in the States for the SCCA GT cars. The rules are written to promote that type of construction too, even imposing a 2.5% weight penalty for IRS builds after 1990. The original idea (post '90) was to create a flexible platform from which one could easily update to various manufacturer engines and/or body styles, even switching marques, but it never really took off. Regardless it's still an exhilarating drive, with good brakes and low weight - typically under 2k pounds. You'd think the live axle wouldn't perform too well, but it does surprisingly. Operating costs are relatively cheap in comparison to other 'spec' classes as well.

Watts are good, very tuneable.
