I have decided against them, thanks guys. Ordering the Performance Pack without Cup 2.
I ordered my 290 last month and came to the same decision to take the sub 8 pack without the cup 2 as they just seem to be a little too compromised. Also, the cups 2s aren't £115/tyre more than the standard REO50A or the Contis you get so not worth the £460 option price in my opinion.
Out of interest, what was the wait time you were given for your car? I went for a Cupra 290 5dr Sub 8 and bucket seats and I was told 18 weeks. I received a call from the dealer last week to tell me that I would now be receiving a Black edition car as you have to order a Black edition to get the sub 8 pack now? It hasn't changed the price or the spec of car I ordered in any way from what I can tell. Anyone got more information on the Black edition?
