GSF is rad - that's a great motor
Comparing it to the turbo cars is missing the whole point of the car. It talks to the driver, makes all the right noises, steers with the throttle and it's not too fast to enjoy blasting through 3-4 gears on a regular-ass day when an onramp opens up or what-have-you. Our W212 E63 is just too damn fast and has too much traction to be playful at low speeds. It's an animal, and getting shoved into the seat is fun, but it's relatively one-dimensional compared to GSF as a driver's car. And it's "slow" compared to the latest crop of ubersedans. And yeah it's fast and fancy and european but it's also already broken a lot, with under 31,000 miles it's had more go wrong with it than my E90M with 116,000 on it. My tundra has 46k on it and has had zero failures and that's likely going to be true at 146k. Toyota's V8's are amazing engines. Buy now and ignore all those M5's and S7's and the like, they may be faster, but all street cars are the same speed as the Grand Tour recently pointed out, what you want is to have more fun on the way there
Of course, you'd also be an idiot to get rid of an E90M, so assuming you're that stupid, you'll ignore this advice
