I don't know about the MFD, but I did just finish looking for 100s. I ended up with an '03 w/115k for $18.5. I saw a lot of 90k or so ones in the low $20s though. Murf did tell me that there are places out there that repair the MFDs just fine.
I started off looking for lower mileage ones, but the prices for those seemed relatively high. But I have a lot of confidence in the brand and will drive it until it's worth nothing, whereas if a lot of non-LC folks will dismiss a vehicle offhand with higher mileage I think.
Personally, I came to the conclusion that pound for pound, higher mileage LCs were a better deal overall. But that's highly subjective.
I'm going to grab mine this weekend, and am really looking fwd to the move up. Good luck finding yours!
