Interestingly, I sent the price I'd got to both Fife and Seattle, and one said "If that deal is real, take it", the other said "In 25 years of selling cars, I've only once done a deal better than that".
Plus, I just called Tiho to check the status on a wheels order he's doing for me, and we ended up having a 30 minute chat about all sorts of stuff. Can you honestly say you'd want to spend time talking with the CAs at "the other dealerships", or that they'd want to spend time talking with you post-sale?
