Brand new civic or corolla dont even come close to the class of Mark X or Crown .As far as your question is concerned then go for Mark x ,its parts are easily available even you can get brand new parts too like suspension and engine components . Finding clean mark X would serve the purpose . Even if you get slightly rough . Spend some money on it it will be more reliable then any Pkdm . Even new cars like Civic for example is facing reliability issues .Whether its a new car or old problem can arise . Rest is your choice !
