Louisa posted:P.S. Has oil cooled been replaced by liquid cooled ?
Porsche now ONLY makes liquid/water cooled motors as they throw off considerably LESS pollution. The EPA guidelines are such that aircooled cars are now a thing of the past, largely to pollute less...... although collectors and PORSCHE aficionado buffs seem to prefer and collect air cooled cars.
Again oil cooled are actually "AIRCOOLED" with a bit of help from oil coolers. Water(LIQUID) cooled have replaced air cooled as they pollute less and are more efficient, better gas mileage. Most replicas are air cooled but recently, folks are opting for water cooled SUBARU motors when building a new replica or even replacing their old worn out air cooled motors with a Subaru motor.
Some prefer air cooled, others do not...personal preferences.
This IM Roadster is likely a great car but any purchase should be prefaced with a thorough PRE-PURCHASE INSPECTION by a master mechanic....expertise by someone familiar with these cars. Very important to have all of that information BEFORE buying so that you do NOT make a bad investment.
No one can predict the future...I bought a brand news 500G BENZ back in 2006 for $85,000 and it broke down on the way home from the dealer....SH*T happens
