Funny how the second anyone gets rid of an Omega, there's very little to actually do to a car 
Whilst new fangled cars on company lease plans are great in principle, I do wonder where the catch is 
I mean zero deposit and low payments on a £70k+ car has to have an almighty gotcha attached to it? Retail leases are circa £2k down and £1,700 a month and you still don't own it.
If your employer are picking up the bill then there's a massive implied benefit, likewise for charging at work.
I hope the car serves you well, and getting shiny things is always fun, I hope you've done your homework.
As you know, big Bro used to frequently lease cars, though stupidly went for a succession of S-Class's until he learnt his lesson there.
His initial+monthly payments (well, his business) came to around 15-17k over 2 years, depending on precise deal, which is less than depreciation on an S Class as I'm sure you know. He offered me an XF Sportbrake for £200 a month (inc the VAT I'd have to pay and not be able to claim back), no initial deposit, 2 year lease. That was a brand new, decent car for under £5k over 2 years, only having to pay for fuel (everything else covered). Shame I really, really didn't want an estate!
Obviously in tunnie's case, half the real cost of the lease is by saving paying tax, making it favourable. I have access to a similar scheme, but it only covers EVs, which is a step I'm not ready to take yet.
So it can work for a lot of people, depending on circumstances and often timing - in tunnie's case, he had to get a runabout for a few weeks, and even that was financially viable. Equally, it's not for everyone.
