Q: Won't accelerate pass 35 mph.

They are fast as lightning cars. I just met a guy who has one, and I was talking to him about the car and we gave it a ride. They are zippy, fast cars but they are pretty expensive. He...

If you want to, you can, it is a very good oil. It doesn't really need to be done at 2500 miles. That's way [too early to change the oil]((https://www.yourmechanic.com/article/when-should-i-change-my-oil), in my opinion. But it is very good oil, and...

Hi there. Actually, that cost is about average as this is a complex job to complete. Replacing a transmission is not a job that our mobile mechanics offer, since it is better to be completed in a shop with access...
