luck. Dont wast your time. A rebuild could be expensive, and depending on the overall condition of the car you might get 8-10,000 if lucky. When someone says 'ALL IT NEEDS IS SEALS ' usally doesnt know the half of it. There is many diffrent variations why the car isnt running, or running correctly. Definetly have a true mazda mechanic that knows what they are doing take a look at it. My friend it may just have a bad hose thats causing a leak, bad plugs, turbo pipe could be lose, or many other reasons. Everybody is always to quick to assume that their rotary needs seals and then goes to a reliable honest mazda tech only to find what others said a cost for a new engine would be, is only something else that is a cheap fix. If you really want this car for yourself, its a nice collectors car. If you want this car for profit dont get it. go buy your dsm's and make one impressive and sell that. peace
