I would make sure you write down and get them to agree to what you want done, like stainless work and what parts/brands will be used. That price could sky rocket in no time like mine did :s Dont ask how much i spent hahah
i guess you could tune some of that out. my worked a12 was like that to, was really hard to get up ramps/stands. I believe thats a trade off for top end power.
