Overall everything went well. The requesting of the original owner for the vehicle keys was never done as I was never notified of a reply.

Blizzard Motors review
Found the BMW online and set up test drive with Doug. Car was immaculate. The deal was easy and I got exactly what I wanted. No hassles. Great little dealership.
2004 BMW 645 review
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!

Mac Haik Ford Lincoln review
I recently purchased a 2025 Ford Explorer from Mac Haik Georgetown and had a great experience. David Soto was incredibly helpful and never pressured me. The process was transparent, especially regarding the financing (0%APR). While we had to spend some time negotiating to get a fair value for my trade-in, I really appreciated their willingness to listen to my research and meet me at a price that worked for both of us. My family love the new vehicle and all premium features (Large screen, heated seats, etc.). I highly recommend this team for anyone looking for a stress-free purchase.
2004 BMW 645 review
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.
