Mazda did Wankel Rotaries better than anyone and by default did Miller Cycle engines better than anyone. But they do require special care and feeding.
The regular Millenia has a KL V6. It is a gem of an engine. Ask any second gen Probe GT/Mazda MX-6 owner. But it is a bit small for the Millenia.
The Mitsubishi Diamante is very affordable, drives pretty well....and a pain in the posterior to maintain/repair.
My late father-in-law had one. The 6G74 3.5 V6 recommended premium fuel, has a timing belt that is time consuming and/or expensive to replace, only makes a few more horsepower than the OHV GM 60° 3.5 V6, and it didn't get very good gas mileage.
The heater core is also expensive/time consuming to repair and fails frequently.
The SVX is funky with it's two piece half windows. Should be regular Subaru H-6/AWD stuff for maintenance and reliability. I've never seen one with a manual.
Don't know too much about the 968. It's predecessor, the 944, was a beast to do a clutch job on, and the transaxle was marginal for handling the 944 Turbo's power (it was fine for the 944S and lesser engines) Otherwise the car was an amazing combination of balance and handling. I've legitimately wanted a mid-1985+ 944 SOHC N/A for many many years. I was (and am) that impressed with it. Just don't want to do the clutch job on it.
The Subaru SVX was not offered with a manual transmission. Also, IIRC, the engine was not used in anything else in the US.
