Congrats on the new ride & welcome.
There is a storage pocket available out there somewhere that replaces the stock cd player, they are hard to find though. IIRC, it's a trooper part & may require some luck at the salvage yard.(use the search function to find out more)
As far as larger wheels/tires, I run both 265/70 r 16" on stock wheels in winter & 265/50 r 20" for my summer skins. Both are large enough to require minor trimming of the front cladding, but it's really not noticable to anyone but another VX owner & takes about two min. Again, try the search function.

Enjoy the new hot rod, Ldub
