I sat in my friend new MS and only 1 week old. We had 5 person in it and wow it was fast with about 2.5 tons on the car. There was 1 problem with the car after the ride. After got back to the car park and got out the car all 4 of use had a bit of headache. Do you guys have this? I think it was course from the speed and the force rushed our blood to the head. correct me if I am wrong.
