Hi,
others may be able to point you in the right direction as to finding the 'off set' wheel. Personally I have no problem with the old standard wood rim, bit tight getting in and out but once settled behind it, its a joy to look at especially with the walnut dash....I just need magnolia dials to finish it off.
IMHO, nothing wrong with Mountneys, but they belong in MG's and old Mini's, luxury British sports cars like Morgans, old Jags and Astons have to have a Mota Lita.
Go to your local dealer and try out the options in the cars on offer...but remember the driving gloves...they really do work.
good luck!!
