It doesn't hurt to make an offer. Saving that much money sure makes it worthwhile to travel. Luckily I have a relatively local dealer (90 minutes away) that came pretty close to the best offer I found from an online dealer. The online dealer required a 6 hour drive, which I was willing to make part of a trip. I figured for a couple hundred bucks I would stay local though.
Good luck. Some dealers are stubborn and won't budge. Seems to me that I would rather make an easy sale and only make a couple hundred dollars profit rather than NO SALE and NO PROFIT.
