Kastelic made the back seat in the Cig and a cover for me, nice job but they are not cheap either and even thou I payed full price that extra money didn`t buy me extra awesome work. They had to come to my house,take more measurements and redo the cover because it did not fit well, still didn`t fit afterwards and the zippers got stuck constantly. They also destroyed my old cover which they used as a template, I wanted that cover. I don`t see why they are more $$ cause I didn`t get a better product.

I wouldn`t be able to afford boating if I didn`t shop around.
$20k for waves and wheels to do the interior, I`m paying $6k and it will look just as good if not better since the $20k wastheir 'basic' start price.

I would think the small little mistakes that may or may not happen during the process, would tend to get fixed quicker for a full price paying customer than a negotiating customer

That`s not how that works.
