Does anyone know what's the difference between RX-8 Euro Spec Vs JDM Spec in terms of engine, body or anything? My wife bought RX-8 last month (used car) and I was told this morning that our RX-8 is Euro Spec by another RX-8 user. He mentioned our RX-8 has two oil cooler where else other spec has one only (overall). What other difference on RX-8 Euro?
