Then you probably have to wait for next year. I think it's a good idea too. I really enjoyed the car. M5 is too expensive, M3 is too small to haul 5 people. A Dinan 5 will be perfect. It gives some 25 more house power on top of the 325 HP, more low speed torque and more rigid body for cornering.
I still hope someone can share some experience. Don't tell me no one in this forum has a Dinan car. What a shame.
