Great responses...So how silly would it be to get one of these for a year or so? My current situation is a 92 accord that has 180k and is days away from needing some major repairs.
The logical part of my brain is saying buy another honda in the $10-15k range, hopefully a prelude or accord with 30-60k miles on it, and have it pretty much worry free for the next several years.
On the other hand I'm thinking I'm young now and most likely wouldn't have an opportunity to by a car like the BMW ever again in my life. So buy it, drive it like I stole it, and fix up the accord and drive that on poopy days. Thus splitting the mileage between both cars and hopefully keeping the mileage down on the 850, so in a years time I could easily resell it for a very minimal loss. Of course that is if nothing major goes wrong with it.
Another option is to just buy a new car, accord is currently winning, and keep that thing for a long time. This route looks appealing because of the low interest rates now and I have never had a new car before only my current accord which I got with 57k miles on it. The problem here is that insurance will be much higher than both of the other options and that is basing it on the 4 door and not the coupe.
I would say I'm 60% for finding a used honda, 20% for new honda, and 20% for the 850.
