I'm looking at getting a road bike in the near future and one of the things I've considered is trading in my MTB at the LBS where I buy the road bike. I'm guessing that this works kinda like trading in cars -- you don't get what you might be able to if you sold it to an individual, but you do get some money and trading in is an instant sale. On average, do bike shops give reasonable deals on trade-ins?
I may just hang onto what I have since I wouldn't get a lot for it: it's an entry-level HT (Trek 4300) that didn't cost much to begin with and everybody wants FS bikes nowdays so I'm not expecting a big payday for a trade-in. I'd hate to get rid of it since I've really enjoyed riding it, it fits me well and we've logged a lot of miles together, and after many years of inactivity it has done a good job of getting me back in shape (somewhat), but the trade-in value would help with the new purchase.
The reason I'm looking at getting a road bike is that almost all of the miles I've ridden the MTB have been on pavement and not on a trail. I dunno... I think I'm a roadie, and might as well get the right bike for it.
