Excellent dude with a wealth of knowledge in getting you the right car that you need. Very well put together and is always excited to start a great conversation. Will help you out on getting all the right paperwork for your state when purchasing the car, not from your state.

good comments all around, spent 7K for new plugs and coils, brakes, rear suspension, etc..on 54K car (2004)and was going to buy new--but, an extra car...worth it...new tires a few years ago and better than most on the road, enjoy

Dre the car sells man helped my sister and I all the way. I recommend this lot if you want to drive in style. Just have your money and they will work with you.

FANTASTIC LOOKING AND TO DRIVE IS A DREAM CAR... LOOK AFTER IT AND IT WILL LAST FOREVER... WELL... NEARLY... BOUGHT MINE FROM MARK N PAUL AFF9RDABLE AUTOS IN ADELAIDE... GR8 FIRM N SERVICE... BMW 645 CI CONVERTIBLE IS THE BEST... FORGET THE REST...

I can?t say enough about how INCREDIBLE the staff at Autonation was!!! The place was very busy, people everywhere, like a mall. Not even two minutes after I approached the crowd someone was there to help me. The transaction was quick and painless. I was thoroughly impressed by the professionalism and attention to MY needs. I would recommend EVERYONE go to the them for their vehicle purchase.

What can i say,i never,ever would be thinking in my mind,that i will bought a BMW. But i did,and i will never sell it. i am so happy with this car. Can recommend this type of car. A BMW 645ci,2004 model.

The best car I have ever owned or driven! Glad I went for the V8.. what power and beautiful sound! Never could think a 2005 car with 90k miles would still feel so smooth. I will NEVER sell it. I can't comment on running costs yet, but I don't care!

I was looking for a lifted new body Chevy, they didn`t have one on the lot at the time. John the owner went out and found me the truck I was looking for within a week at a great price and kept in contact with me while he was finding me a truck.

I was shopping for a convertible vehicle..I had a few choices in mind.But I went with the 6 series.I love the style and performance. This is my Dream car.

Need to stay up on maintenance. Check for leaks when purchasing. Also check tires and engine check for any engine lights are on Check gauges

Andrew and his staff were AWESOME, from the moment I was on the website, to the moment I walked in the door, very honest, straight forward, no high pressure… I’ve looked for weeks to find the car for me, Andrew and his boys made my experience for enjoyable. Could not ask for a better experience.

Joe has been very knowledgeable with my questions about the vehicle I'm interested in purchasing.

my 04 with 53K is a stud..about to upgrade brakes and suspension just bec of age...don't feel anything wrong..but deciding to keep vs new..her stable mate a 2022 M760..but still love her..would need to part with 200K for the same smile...looks brand new and always complements...20-25? before i upgrade?

Ralph was helping me and he was very attentive during our communication. He was very straight forward answering my questions.

Bought my 2004 645Ci convertible with just over 41K miles just a month ago and haven’t stopped smiling. Handles like a small euro-spec cabriolet despite its size. Time will tell how reliable it is, but first owner clearly babied it with regular dealer services. Very comfortable standard seats and a fast V8 that could be scary fast to some. Could not find anything close to this car in terms of design, high-end finish, and performance for the $15K I paid. Get one!

Thanks to the kind gentleman at southwest auto sales for a stress free easy going fair deal . Thanks to Jesus and Jose these men know how treat a customer and I would recommend to any one✨️✨️✨️✨️✨️✨️✨️✨️✨️✨️

I love my 2023 Frontier. Thank you Naomi. They made the buying process so easy and enjoyable. The service dept. has been nice to work with as well.

The only way to own a BMW 645 is to have a convertible and 6 speed manual transmission. Fantastic combination that offers fantastic performance. Press the sport mode button and the BMW 645 becomes a barely containable beast! The ride is very comfortable. Not overly firm. Just enough bounce to absorb the harsh bumps in the road. The car handles very crisply with the standard suspension setup. Adding the sport package gives you active steering and that makes an already well handling car handle even better. Steering wheel movements are precise. I strongly suggest looking for a car with the winter package that adds heated seats and a heated steering wheel. Seats are very comfortable. Long trips are an absolute joy. Don't be afraid of long trips away from home. The BMW 645's trunk is much larger than it looks even with the soft top storage try down. There aren't to many negative's with this model. The few complaint's I have is.. 1. Only one cup holder 2.the i-drive on early and later models is archaic. There is no Bluetooth, USB, or AUX port on 2004-2006 models. There are several aftermarket solutions available for the consumer that can be added on. 3. Despite it being such a large car the back seat seems smaller than my old BMW 3 series convertible e46 model. 4. The Guage package is seriously lacking. For some reason BMW decided to remove the traditional fuel economy Guage that has graced BMW dashboard's for nearly 40 years. There isn't even a coolant tempature Guage. But, there is an oil temperature guage. I find this all odd. I would have liked to see the fuel economy guage and an option to look at the readouts through the digital readouts that the driver can scroll through. Again, there are aftermarket solutions if the lack of these instruments truly bother someone. The reality is that most of these issues fad away when you start driving, drop the top and hit the gas. The smile on your face will be ear to ear. What to look for when buying a BMW 645? As with every used car purchase it's buyer beware. However if you must buy a used BMW look to see if proper maintenance has been preformed as well as the few major weak spots of the 4.5 liter V8. These engines were known for their excessive leaking of oil and coolant, burning oil and tail pipe smoking. There are 3 repairs that can be costly for an individual but relatively inexpensive at the dealer level as these repairs have become routine. Look for cars that have had oil valve seals, valve cover gaskets, timing cover gaskets, and anything else associated with an oil leak or oil burning repaired. Also look for cars that have had the main coolant pipe replaced as well. Once these repairs have been done they are life time repairs for the most part. Outside of those 3 issues these engines are rock solid can take a ton of hard driving. With proper maintence these motors will last hundreds of thousands of miles. I highly recommend the BMW 6 series.
