You can go to about an e90 and still have a good cold start. We run a starting agent in our platinum E90 to overcome the cold weather unlike all other e fuels that will drop to a E70 and use the extra fuel to help start it.
It would be my pleasure. I also drive an auto territory turbo with a 4 speed domanelo built box and convertor and yes the wife also drives an auto terry.
You will never see an auto in this car it's my street / strip car I will hit an eight in her and faster. Baby steps. If I wanted to drive an auto il take my wifes car out because that's who drives them in my family.
