Personally, I bought my car through Chris Perman @ Executive Cars, a dealership in East Hanover, New Jersey.
Chris was absolutely amazing, showing me real value on the phone the first time we spoke.
I live in Ottawa, and when I first found the car on Ebay, I called him directly to make an offer, but I wasn't sure of the logistics of getting down to pickup the car and drive it back.
During the process, Chris handled all my paperwork with care and urgency. When it was time to fly to Newark, Chris picked me up at the airport, drove me 30 mins to the dealership to pickup the keys, fill the gas tank and then I was happily on my way home to Ottawa which was a beautiful drive through New York.
I highly recommend working with Chris, he's honest, helpful and wants you to be a happy customer at the end of the deal.
Chris can be contacted at chris@executivecars.com, do check out his inventory, they may have something you are looking for.
