If you want a completely easy car buying experience, you need to check out Speedy Car Loans. They have helped tons of people obtain financing for vehicles as well as hunted the right vehicle down and delivered it to the buyer (it seems that a huge amount of their business is referrals from other super satisfied customers - keep that in mind). It constantly boggles my mind on how they can make any money when they are doing all this extra leg work to ensure that the customer gets exactly what they want, with the least amount of hassle I have ever experienced (the dealerships surely don't go to ANY length to do anything other than snow the buyer and attempt to get that sticker price which is a huge markup anyways).
Basically the process here is auto-pilot: Fill out the application on their website, discuss with their knowledgeable staff what the particulars are for your situation (financing, money down, trade-ins, desired vehicles stats), then wait for your car to arrive.
I really can't say enough good things about our experience here. I would completely recommend these guys to anyone looking for a ride. Actually, I am about to call and see if they do motorcycle financing as well.... stay tuned!
