Hey InitialM,
Here are my thoughts, 2 cents worth having own an E38 myself
1. If looking for single vanos variant, you're then in the 1994 - 1998 market. Most likely you will find one in the 1996/97 year of make. The price ranges between RM45k - RM60k dependent on condition etc. Because of the year of make, it also rules out commercial financing, however financing at higher interest rates for shorter terms are possible e.g. Public Bank offers 6% for 4 years etc for a 1996 car. That's alot of interest to pay. So in reality, you may end up having to purchase your dream 1996/7 E38 Single Vanos for cash
2. Just like any dream ride which is gorgeous in asthetics (and I fully agree that it is by far the most gorgeous 7 series ever made, maybe the F02 is coming close la heheheheh) and ride comfort with all the bells and whistles....maintenance will cost you a fair bit. In my opinion, the E38 I own was very well maintained previously, but with any car that is like 12/13 years old, you would expect wear and tear that needs careful attention. Based on reading your E39/E46 thread, you are a perfectionist for the perfect UDM...not just talk, but you walk it!!! That's absolutely admirable, so expect maybe a 10% - 20% hike on the current maintenance costs of your E39 for the E38, in my humble opinion
3. My personal opinion is that making the monthly payments and roadtax/insurance on a car is not the test, because generally you know your limits and you can work with 1 or even 3 cars with your set budget. E.g if you wish to spend RM4k a month on a car instalment, you could choose to buy a brand new E65 525i, or you could buy 2, 2nd hand UDM's and still have some spare change. Choice = opportunity cost. My consideration has always been the unexpected maintenance, which I guarantee you is something one will experience at least once, if not more in their ownership of an aged car, whatever make it maybe. Unexpected = big cash layout at one go : )
4. I am a true believer of you only live once, so enjoy. But I am also a true believer of never throw good money over bad. I personally would feel the heat owning 2, what more 3, 2.8 litre cars!!! But I do admire your style, dedication and love for your UDM's....it is truly insipiring.
Let me share with you a dream that my mom every once in a while reminds me off...when I was 13 years old, my mom reminds me that I said to her that my dream would be to own a 3, 5 and 7 series, all at the same time. I have achieved half of my dream, i.e. at some stage of my life todate I have owned a 3, 5 and 7 series UDM, but never simultaneously......I am yet to grow the ***** to live my dream!!!!
So InitialM, having said all that I have said......you should live your dream
And if you do go for an E38, pls don't start a blog on it....cause I know i'm gonna go broke wanting to follow in your footsteps....hahahahaha...tak boleh tahan
All the best man!
