So I have now my 1996 XJR6. The one major upgrade I want to do to it is the 18" alloy Penta wheels off of the 98-00 XJR. They're very hard to find as I've been searching (at least for a good price) but I have now located a used set for $1400 not mounted on tires.

My factory 17" XJR6 wheels are immaculate with about 70% tread left on Pirelli tires. I know I could get a grand for those or so and someone on this forum not too long ago had posted looking for these in the Wanted section.

If you were me would you guys sell the exclusive XJR6 wheels to make buying the other XJR wheels much easier (I just graduated college) & cheaper for me? I am keeping this car FOREVER so the current wheels would honestly be sitting for years in my basement or garage and the tires will eventually dry rot in time and then they will be of no value....just don't know if letting the original wheels go on a 58K mile car is a good idea?

And is $1400 for a perfect used set of Pentas a good deal? I'd still have to buy tires. They're coming from Michigan to Buffalo, NY. I keep comparing them to last summer when my dad bought a used set of 19" factory alloy BMW wheels with great tread left on used Pirellis for his 7-series shipped from California for only $1200...did we get an awesome deal then or are these 18" XJR Pentas more rare and people will pay more for them??
