Best place to look is whatcar.co.uk at leasing deals. Mine 2 years, 8000 miles. Doing 2 years as won't need to have serviced and 2 years @ 8000 miles won't need to change tyres. If you do 3 years or longer you will need to replace tyres and service costs. May as well save the £800 you would spend on tyres an use it for your deposit for your next one instead!
Best of luck with the new car, sounds great. I also prefer 2 year lease deals but my experience is a little different to yours. It's also worth a look on the Contract Hire and Leasing website which is a big search engine just for lease deals, although saying that I have arranged my next car through my local dealer as they were able to beat all other deals I've seen.
I got my Cupra
280 5 door in July '14 on a 2 year lease, 8,000 miles per year which was my mileage then, it has since dropped due to a change in circumstances, it's now done just over 12k and goes back in 5 weeks time. Mine was set to the variable service interval by the supplying dealer which suited me fine, the car will tell you what it needs and when - if you don't stick to that you can risk falling foul of the lease company which is fair enough. My car needed an oil change (£139 at main dealer) after 12 months and has just had it's first inspection service (£179, also main dealer) a couple of weeks ago - I expected to service it once in the 2 years so fair enough.
I was hoping to get 2 years out of the tyres too but the fronts didn't make it, the original Bridgestones were never up to the job, with hindsight I wish I had changed them long ago as the car is so much better to drive now. If I'd been keeping the car longer I would have looked at Goodyears or Michelins but went for Avon ZZ5s as they seemed a good compromise between price and quality (£177 for 2, fitted) and they are fine so far (apparently they aren't the longest lasting but that isn't an issue for me).
My new Cupra
290 arrives early next month and I'm keeping my fingers crossed that it comes with Contis on rather than Pirellis based on the other threads here - I reckon with a slightly lighter right foot it may be possible to get 12K out of them but time will tell, I didn't get the car to drive it like a nun
