Here's another thought to ponder...
You never know what the "market" will tolerate, until you try it.
As of the past year or so, used alloy CSXs have been going for the 125-150k range. Glass cars were in the 65-85k range. Now glass cars are closing in on 100k, and alloy cars are going over 150k.
It doesn't hurt to try. We all would like to get as much as we could for something we are selling, right? Nobody here would say "na, I won't sell you the car for 200k, because it's only worth 150k, so just give me 150k", if someone were offering 200k.
The only way to find out, is to ask
