Do it bro. After I bought my house I bought the first F6 about 6 months later and the extra debt just made me work harder to earn more money! Buy a low k BF MKII XR6t with a ZF and slowly mod away when you have some spare cash. I have to agree that putting a car on your mortgage is silly because the car depreciates a hell of a lot faster than you pay it off, but if it means you get into a t then go nuts. The appreciation of your house will outwiegh the extra debt after a couple of years depending on where you buy
