Lexus of Route 10

I am currently shopping for a lease on a 2008 Lexus IS250. I'm a frequent reader of the forums on Edmunds.com so I'm very familiar with the money factor and residuals available on the car. I initially called Warnock Lexus and was put in touch with one of their internet sales managers who was very polite on the phone while I asked him what the current residual and money factor was on the IS250 for August, as I like to ask these questions to gauge the salesperson's honesty level. He quoted me a number that was very close to what the Edmunds.com host had posted on the forum (1.44% vs the correct number of 1.34%) and gave the correct residual. I then went in for a test drive and that went basically according to plan, except that I'm looking for the manual model and they "didn't have a demo in manual" so I wasn't able to take the car they offered (with a manual) out on the highway which is almost unacceptable. I then emailed the dealership the next morning with my offer but they countered and asked where I was getting my numbers from. I explained the entire deal, including MSRP, Cap Cost, Residual, MF, etc. Now the same salesperson, obviously forgetting what he had told me 24 hours earlier, said the interest rate was 2.5%. Now this is classic interest rate padding and it' really sad that a Lexus dealership, and Warnock is an "Elite" one, are playing this game. On top of this game, the salesperson also questioned the invoice pricing I got from the Edmunds.com website, and he explained that their dealership pays a different invoice price, which I found even more pathetic than the interest rate padding. I would strongly recommend staying away from this dealership unless you like dealing with polite, but dishonest people.
