Chatting to Wheelbase now. Will update with photos if I go for it.
Man maths required...
Don’t forget to consider what you’ll be doing with your existing alloys.
It might be tempting to sell them to help offset the cost of any new alloys you buy, but when the time comes to eventually sell your car many (most?) prospective buyers will expect it to have the original factory wheels fitted and could be put off by a set of aftermarket alloys.
With my last three VW’s I changed the wheels but always kept the originals and put them back on the car prior to selling. With two of the three cars, the buyers said they wouldn’t have bought the cars without them having the original factory fitted alloys, so ensure you’ve got space to store them safely.
What about selling on aftermarket alloys if / when you put the OEM alloys back on the car? IMHO you shouldn’t have any issues selling good quality aftermarket well cared for alloys. I sold all three sets of mine with no issues and got the price I wanted for them. One set sold on the day I put them up for sale! Good prep for sale (thoroughly cleaned - both sides), being honest about their condition (e.g. any damage, repairs etc.) and plenty of pictures always helps with the sale.
