This is belated but amazing spot. I was heading to a weekend festival (hence no phone signal until I got back today) last Thursday morning and spotted two of my twins within a few minutes of each other. I have a white/magma M40i and on the M1 North just before the Luton junction I passed a 4--cyl white/magma and shortly afterwards I pulled in to Toddington services to find another 4-cyl white/magma parked there. The latter was number plate KAZ ****, which might be the same car I saw in the city last month (look up 6 posts from here).
