I priced weatherstripping at a GM dealer for the tops, doors, windows and it came to around 800 bucks for all of it. A bit higher than my anticipations. I want GM because I am under the impression that it is the best. Are there any alternative companies that can make a comparable product quality-wise?

$250, a lot better than 800!
