Would I be nuts for considering a high mileage (100k-125k) 10 year old year 650i?
Are they reliable?
I do about 13k miles a year and my last car was a ST220 where I averaged about 26mpg. Am I likely to see a considerable rise in fuel costs with the 650i?
I've never owned a BMW before and don't know much about them in general.
Yeah something has definitely gone wrong. This is for a 2006 Z4M with 57k miles. It won't even allow you to select a zero excess either.
Thanks for that info.Perhaps a little bit... 650i running costs could be quite a bit above something like a Mondeo...
For fuel economy, you will be lucky to average 20mpg... perhaps 25mpg on a gentle motorway cruise. Heavy foot and that will happily drop to 15mpg or less.
Reliability, well... that depends on the example you get. Get a good one and it'll keep going for another 100k miles or more without needing much more than a service... get a bad one and you'll be in for some hefty bills.
At that mileage and age, expect the suspension to need overhauling and some other intermediary work.
If you can find one where that type of work has been relatively recently completed - then it might be worth going for.
If you're looking at one where nothing has been done for the last 3-4 years... then avoid it and look for another.
Get a good one though, and you'll love it - especially a nice upgrade from a Mondeo - nicely well-rounded cars
The engines and gearbox on the 650i are very solid, they are decent reliable cars and can be remapped to close to 400hp
Economy i dont think you'll find them a whole lot worse than your ST220 - that old Ford V6 is an absolutely woeful engine when it comes to that - it seems to suck fuel at the rate engines twice its size do.
Really? 30-40bhp extra from a naturally aspirated engine with a remap? Blimey.
They're not that bad. A couple of MPG worse than the BMW 3.0 M54, perhaps. I could get 35-37mpg on a run in mine. Hardly "woeful".
From the ST220 thread it seemed your fuel economy was the exception to the norm Howard judging by what everyone else was averaging.
From the ST220 thread it seemed your fuel economy was the exception to the norm Howard judging by what everyone else was averaging. It depends where you drive as much as how you drive it I guess as a change of job increased my fuel economy by over 20%.
In other words, I find it hard to believe the economy from a 4.8L V8 in a heavier car won't be a good deal worse.
I'm impressed you can get so much more power from the 650i with a remap though.
You'd be surprised at just how "frugal" some of the large V8 engines can be in context when compared with smaller V6 engines.
Fuel consumption is certainly not linear, and generally the larger engined cars will have gearing which favours lower engine speeds. Its sometimes quite surprising how much fuel a V6 will use, a much more powerful and larger V8 often wont actually use much more.
