Hi sas pinkie
From memory they are seven feet one inch wide (plus mirrors).
Most mechanical parts are easy to obtain, engine common to other American vehicles, have ordered parts from Kascar in the states and they have arrived within THREE days, have waited longer than that to get parts for my Transit van!
Soft top/Cargo is the best to drive particularly in summer with no doors, Slantback best looking but very noisy to drive and poor visibility. Cargo easy to convert and slant back kits are available.
Power steering and automatic transmission make driving easy.
Importing one from the states is likely to be difficult, many sellers will not even consider it due to the laws preventing the export of military equipment.
I guess that fuel consumption is in the order of 14 to 15 per gallon, I don't do enough miles in mine to worry about it.
Had mine for 2 years and have no regrets.
If you want a ride in one to help you decide, let me know I am also in Suffolk (Near Ipswich)
