Buying a new bike very soon. My lbs has a '13 trek stache 7 leftover. Retail on the bike is $1760. He said I could buy the bike for $1,389. I would also not have to pay tax due to certain reasons. I love the color and the features/specs. I want to try to get him down to $1,349. I am also looking at a '14 xcal 8 for $875. I test rode that bike and loved the feel. Didn't have a chance to ride the stache. Is it worth the extra $500? Thanks. I love this site, very new to it.
