I was cruising down a Mexican highway going around 60mph in my 2015 2dr 6mt MAP Stage 2 e30 tune, and I noticed a new white BMW 750i with tinted windows was cruising behind me and riding my tail. He was driving pretty aggressively and I could tell he was waiting for the lanes to split into two so that he can pass me. I instantly got the itch to gun it, but I waited until the split so we can both punch it at the same time....Right after the split, we both punched it and to my surprise I started pulling on him, and by the time I was almost about to shift into 5th, I was about 2 cars in front of him...and that point he just let off. He then got next to me to try again two more times, same results . I really didn't know what the 750 had under the hood so I didn't think anything of it..... but I checked the specs later on and the car has a twin turbo v8 with 445hp, and runs a 0-60 in 4.3s and the 1/4 in 12.7 @ 112mph! It was pretty quick for a 4500lbs.+ boat!
