Leasing - Informal Extensions & Maintenance

[Sim75]

I have an X3 M40i on a 3 year deal with Lex, started just before the pandemic hit.

Car is awesome.

Normally I'd chop in after 3 years and just replace with something else, but the prices are eyewatering and orders are taking 12 months at best!


My contract says I can keep this one for a maximum of 60 months for a small uplift (circa £50) - as an informal extension.
I'm guessing that a formal extenion would see the price skyrocket as the car is now being quoted at double what i paid.

Anyway...

I paid extra for full maintenance, so does this just continue into the informal period?
I'm guessing it does as there's no specific wording to the contrary excpet that the terms and conditions of the existing contract will just continue.
Things could get pricey as a big service will be due and also tyres will need looking at around that time too.

And before anyone asks... Lex have no email address to contact them on and the last time i called i gave up after 50 minutes!

If anyone could provide one (contact email) it would be handy!
