Hi All,
I have recently acquired a BMW 630i (Y2006). I would say that first of all it might be underpowered compared to a BMW 335i but then again if I would like to see the glass being half full, I can think of it as being more powerful than a BMW 320i.
Anyways, I would say that I bought this 630i because I really think it looks great (my personal opinion) and ever since they have launched it, I have always wanted to get one... I had to wait couple of years to muster some courage (buying a Bimmer is a big commitment

) and most importantly imagery paper of our Duli Yang Maha Mulia ..

With that I have finally got myself my 630i!
I would say that I truly love it. I use it as my every day car (yes I only 1 car!)... So for anyone out there who would like to get a BMW 6 series, you might want to consider the following:
1) Do you really like the shape? Some say it looks beautiful. Others say it looks like half cut E60 with an ass of a Beluga whale!

However, everyone is entitled to their own opinion. Most importantly, you should like it (cos you are gonna drive it, clean it, maintain it & pay for it!)
2) Where is this car from? Japan? UK? Well there are a lot of debates on this. Mine is a Japan spec. I had to install a Smart Player to play radio (which comes with a usb dongle). It is not very expensive (transmits radio via fm freq using the car's antenna) and better than installing a booster. Non-functioning GPS as well but I am not too perturbed as I plan to retrofit the new CiC. In the midst of budget planning for this.
3) What are the features in this car? Smart Key? PDC? DVD? GPS? I-DRIVE? U-DRIVE (just kidding...)
4) What is the condition of the car? Does it look new? good? A point to note. If the car looks ridiculously NEW, then you might want to check out if there were some body work done. Difficult for a laymen (like me) to tell this BUT you can do what I did. Make the seller bring the car to a BMW workshop of your choice and perform a diagnostic, under-carriage check, and engine check, etc etc before committing..

It doesn't matter if the seller thinks your being kiasu or kiasi or weird. At the end of the day, you will have the bear the brunt and glory of your baby...
5) Are you buying from a reputable seller? used car? owner? I got mine from an expat who was leaving the country. Sometimes you might get lucky like that. However, it doesn't mean all used car dealers will try to cheat you. The previous owner got the car from a 2nd hand car dealer. So it all depends on how & where u look at..
6) R3... Research + Reading + Reviews. Make sure you read a lot. Forums, reviews, videos, etc on the car before you take the plunge.
7) Financing. I think this is quite individualistic. Some buy cash. Some buy via loans. So, you would need to know how much you can budget for monthly payments, general maintenance (if you are a heavy driver and need to perform 3 services a year and each service costs you 1,200/-, then you can do this calc: (1,200 x 3) /12months = RM300 set aside). Also, set aside for other sudden repairs (if any)
8) 630 vs 645? Ideally if there were no road taxes and petrol was RM1.00/liter (RON97), I would go for the 645i.

However, since we live in a less than ideal world, I improvised with a 630i. However, if road tax and petrol is the least of your concern OR if you are going to keep it as a weekend car, then by all means go for the 645.
Well Sir. Those are my advices. I am not sure if they were/are helpful. However, if you have any other questions, please feel free to ask me... More than glad to help.
Cheers.
