This car is not the best in any category, there are better looking, faster, cheaper, whatever the category. But as a package, this car is the one to take out on a winding road on a Saturday afternoon. Or you can just drop the top and actually enjoy your drive to work, as I do. It has all the power you need to be pushing well to the right side of 100 by the end of the average on ramp. It sticks to corners like glue. And yet is behaved enough to not look like you are finally living out your high school fantasy - even if that is exactly really what you're doing.
Unless you have deep (very deep) pockets, or are comfortable doing routine maintenance on a high-tech vehicle, the 645ci probably isn't your best choice unless you're able to purchase an extended warranty. I drove a 1984 633csi for about 20 years -- thoroughly loved the car. When work required more travel, I upgraded to the 2004 645ci. I was able to pick one up a 2-owner with 85,000 miles for right around $13K. Financed through the credit union and added a $3,200 3-yr/36K bumper to bumper warranty; total price $16.5K or so. (warranty paid for itself the first trip to the shop when the transmission started leaking -- $5,300 expense; I had to pay a $100 deductible). The Bimmer is a FANTASTIC touring car on the road and fun to drive around town... Has plenty of power and a beautiful and unmistakable design.
This is a magnificent car, providing more niche-fillers than any other car on the market: a true sports car, with excellent speed and handling, top luxury, eye-catching look, available with a stick, and a back seat and trunk that are actually useful. However, the alloy wheels are so soft I'm on my my third set, and despite their advertising, BMW will do anything to avoid having the warranty cover anything more than the usual minor issues. The software on the care is unreliable too and the car is a gas hog. Even so, I love it, but it's hard to accept being treated poorly by BMW given the nature of their advertising and the cost of this car.
Love to drive my 645 when the roof works which is not very often over the last year. BMW can't fix it after 4 attempts on my nickel and I can no longer afford these repair bills. Like some women, this car looks absolutely terrific, but don't even think about getting too close. It'll cost you! There are other cars out there that are a joy to drive, do the right thing - buy a coupe!
I purchased my first BMW in 1987, a BMW 325is. Since then I have owned a BMW 528i, 328i convertible, 1988 M6, 540i, 745Li and now I own a 2004 BMW 645ci Convertible. I will tell you this as a prior BMW owner this is the best BMW I have ever owned. I love this car so much I can't bring my self to even drive it in the rain. I only have 14,000 miles on the car. This car turns heads, causes other vehicles horns to blow and lights to flash when approaching. My Lady always wants to a company me in the passenger’s seat. She's is nobody's fool. She knows wherever this car goes there is a lot of attention given and she enjoys being apart of it. This is truly an Ultimate Driving Machine.
