I have an 85x Sportline Plus with the advanced pack, to be honest you’re not missing anything from the basic spec apart from the all wheel drive and bits of black plastic trim given the £600 difference in price.
If I was ordering an Enyaq again it would be an 85 Edition. Yes I’d miss the Matrix headlights and HUD from the Advanced pack but I wouldn’t pay the £2035 for it again.
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
