Hi Morris 14 I'm working over the next few days, i'll try to put something up early next week & thanks,
@Scrumpix - Great looking forward to it!
I have noticed a lot of Japanese cars were either changed when new in showroom or soon after to 'older style looks. The Japanese seem to go crazy over the retro stuff. Just thought I'd mention that as you car could have been extensively changed from original right from brand new. Do you have pictures?
Also, just answer your questions, I've had numerous minis over about 40 odd years and if the wife has her way this one will be the last. 
Regarding matching interior to exterior, i suppose it depends on the colour and your taste. I'd probably like black with matching inside but bright yellow?......... I'd probably be sick each time I saw it. My mini is what I call 'safe' inside, grey and walnut.
@peter-b - She's a great last car to be fair! If the 40 year journey ends is most certainly not a bad car to finish in!
I think what your sayign here is great - grey and walnut is very clean in my mind! I have a Walnut facia myself so i'll definitely be looking to keep it!
The Japanese Minis all had 'Rover' on the boot, so that's correct. I think they also had a Rover badge on the front.
The VIN plate should have some indication of the model BUT the LEs usually appear as City or Mayfair, so that's not much help.
I'm pretty sure you've got an export spec 35 LE, with a 1989/90 interior. This (http://digilander.li...iniguest40.html or http://www.france-tr...nce-709194.html) seems to be the same model, presumably with the correct interior trim. I guess Rover felt that the UK-spec 35 wasn't the image they wanted abroad and went for something more tasteful (though I do like the UK version!)
It seems the decals are available: http://www.miniworks...mini_35_cl.html
Plus if you do want 'original' seats then cream leather as per the 35 Classic is easier to find than the trims of most of the LEs which no longer exist - a pain for those of us who want to keep things original.

@ Some1158 - So what I have come up with is the following;
VIN Code: SAX-XN-W-A-X-K-B-D-08 (Color Code: LVD = Charcoal 1994 - 2000)
1990 On (1275cc cars only)
SAX = MG-Rover
XN = Mini 1275
W = HLS, Mayfair
A = 2-door saloon/sedan.
X = 1275 SPi (standard compression ratio, 9.4:1) Single Point Injection
K = RHD, Automatic
B = 1275 (not special edition) (I'd imagine this would be A - if it was a Mini 35 right)
D = Longbridge
So you are right - the VIN only clarified some aspects! I also came accross some interesting info here;
MODEL (Engine Size) YEAR(s) PREFIX Starting from Chassis No.
Mini Mayfair (1275) 1992-94 XN-WA 049349
Mini Mayfair 1.3i (1275) 1994-96 XN-WA 058254
(As Mine starts with 088 - it appears to be a Mini Mayfair 1.3i (1275))
You mentioned "I'm pretty sure you've got an export spec 35 LE, with a 1989/90 interior." to my understanding the LE was released as a Cooper 35 LE in 1996, as mine is not a Cooper and registered at 1994 (Boot latch confirms this at 12/1994), i'd imagine its either one of the following;
Mini 35 SE
Mini Mayfair (1275)
Mini Mayfair 1.3i (1275)
Again I could very well be wrong in this respect!
