No there's still plenty of the old K models still cruising about. In fact if you believe all the mumblings from the south side, all the J models are all going to be melted down into pots, pans and fence railings to help the war effort whilst the Ks are all going to be extended to the 2525 - if man is still alive....
But seriously....
Some of the K models are currently being modded and "upgraded" into Mk 3A models. This apparently involves adding all sorts of secret bits and bobs to the 34 year old airframe.
This is similar to the actions of those 17 yr old yoofs often featured in the magazine "Max Power" - you take a £100 1.1 Nova GL rustbucket and stick an incar DVD player in it, a £700 Bose hifi in it, a £1000 Irmscher body kit on it and some £2000 Advan 20" alloys on it. It might look a bit "better" (to some eyes) but doesn't go any better and is still a 1.1 GL Nova rustbucket underneath.
No, but seriously....
A lot of the stuff in the Mk 3A upgrade is top secret, the only thing I can reveal is that barrels, such as the one depicted below, have been spotted both at Marshalls and Lyneham.
I'll say no more............
cat, pigeons.....GO!
