Thanks for the reply guys. The only benefit I can see of the 220d is fuel economy, the 200d also comes with a fair few negative though.
IS250 Auto... 130ppltr= 5.85p gallon @ 30mpg over 18k miles = £3510
IS220d... 135ppltr= £6.08p gallon @ 40mpg over 18k = £2736
So it's going to cost me £750 a year more to drive the petrol and that’s with me under playing the petrol MPG and over estimating the MPG of the 220d, they could in real life be much closer. However the 250 is much nicer to drive, cheaper to buy and is likely to be much more reliable. Plus it'd be an auto, better looking and faster. On the whole, given the cost to buy and the repair bills I’m not sure I’d really saving anything buying the 220d, ok I might save a few £100 a year, I just don’t think it’s worth it though tbh. The fact that Lexus can make a 4 pot diesel that’s still no cheaper to run that a 2.5 V6 over 18k a year is a little disappointing, unless I’m missing something?
Is there anything to look out for when buying an IS250? I'm assuming as they are N/A V6's they're solid. How do they handle the mileage? Is it worth buying approved used, if so what is there to be so scared of?
Thanks
