If you want to go e85
There's a rocker switch where you'd normally find the economy/ power switch. Looks like a steering wheel. Will light up a similar icon on the dash.
This is on the c34, not sure on m35?
Highly recommend you get a professional to do an inspection and comp test. I can guarantee the mileage is wrong and you may have some trouble with the aftermarket alarm that's fitted. Apart from that it looks half decent for the price
Got a link so we can check it out?
I've got a nismo 260rs. It's got suspension, brakes, air filter, exhaust, ecu and possible clutch upgrades. I'd imagine the mines spec would have similar upgrades.
