It has been years since I drove a E70 without sports package, so don't quite remember to tell you the E70 vs. F15 "non-sports feel drive comparison". Wish they had a sports pack F15. But it feels lighter than E70, the 35i feels more powerful on F15. Steering is much lighter. Handling feels better. The ride is similar to F10 5-series, like F10 on stilts.
