Ok; maybe I am a little slow but, if you Pay the $899 does that mean they will fix anything found wrong at the agreed upon purchase price? Is there any warranty if they say something is good and it fails in X number of days?
First off I think a good independent survey by a tech of your choice might be more in your favor. Next if you get some quotes for an independant survey and they are offering some type of fix/warranty will they meet the quote?
Seems to me $899 to check out a coach they really want to sell you is a little steep. Just wondering but if this "unbiased" survey showed the coach had major issues would you still have to pay for it even if you don't purchase the coach?
