It's driving me crazy not having anything to work on. I can't find any wide bodies anywhere and I can even find any good regular body candidates!
I just can't imagine that if I did the bolt on, cosmetic, updates to an already flared wide body 911 Cabriolet that doesn't need any engine or trans work, (to make it look like the picture below) that it wouldn't sell for at least $35,000!
If my price was less than $25,000 and I put $5,000 into it, that would be a decent profit.
The one below is priced at $350,000 and obviously is WAY over priced even with the cost of the twin turbo mega engine, but it's the look that the buyer will be mostly paying for and that look will not be hard to duplicate.
I HIGHLY respect your opinion, so please tell me what I'm not taking into consideration.
