Salary sacrifice

Congratulations. Make sure that you have to pay the lease up if you leave before the end. e.g. you decide to pack up working altogether. Even company cars where I was (last ones were Arval provided) meant if you resigned and had a company car, you were liable for some other lease termination fees.

Thanks Rob. And yes, NI is the real benefit of Sal Sac over other schemes, even those that escape Income Tax.

There are a lot of sums to do, of course. Presumably the leasing rate I need to look at is the one that includes VAT, just as with my Cycle to Work bike. Based on that, it looks like a single-motor EV6 might cost me about £370 a month, including the BIK tax; an iX3 would be more like £590. Taking those as lower and upper bounds gives me an idea of costs against which to measure other options, including buying my own.

Congratulations on the new position.

If EV is the new route for five figure annual business miles Tesla could be the most cost effective way to go given their charge costs Vs other networks.

I’m honestly not being deliberately impish here!
But, there would also be a case perhaps for using/trashing the CLS over the next year or three by using it as a work car. Presumably it is long since paid for and it’d be a comfortable thing to hack about in while taking whatever car benefits your new employers are offering.
Even if you had to pay ULEZ charges now and then it’d still be way cheaper than funding a new car wouldn’t it?
Also gives you a chance to establish whether this job/company really is for you without committing to a car contract.
None of my beeswax of course, but it might be what I’d do.

Financially, of course you could, but there's more to it than that. The CLS is fast and spacious and smooth and comfortable, and isn't about to wear out. But I really should not be using a 3-litre fossil engine for my hacking about any more, especially if I'm going to be doing more of it. And, frankly - I know you think this is preachy but it's still true - nor should any of us. 300MJ per 100km is just profligate when an iX3, from my own experience, uses 60 - which it could get, as Esp's Hyundai already does, mostly from a solar array. ULEZs aren't there as an affront to honest 'motorists' but to try to keep cities habitable. And it's absurd that we have known about the climate hazard for 40 years but petrol still costs less in real terms today than it did in 2008 because no politician wants to tell people that lives and assumptions have to change.

And part of my new job will be advising clients on how their IT systems can be more energy efficient in themselves, but can also improve the company's own environmental and sustainability performance. They may not notice what I park outside, but if they do, I'd rather not have to mumble something about it being cheaper.

Trouble is, someone's going to be hacking that 3-litre soot chucker about for years to come yet. If you want to get any money above its scrap value back, that is.
