tbh, nick and I looked at this a month ago, the guy wanted silly money at that point, the GXL is just the European version of the 1300E, with some obvious differences, it was available in both LHD and RHD, 2 and 4 door, and some late 1300Es like my blue one have the GXL designation on the body plate and do carry the same clock, which again was denoted on the body plate, if it was 2 door RHD it would be in my workshop lol, but 4 door lefty, we walked away, if your gonna take it and modify it so to speak, probably worth the 3.5k, but if you going to retain originality, its expensive as it will take years to find the correct parts, if at all, it was a rare beast to start with, now its very rare and so are the parts, even the missing spot lights are GXL specific
the clock and pod RP, are relatively easy to get, but expensive, trim virtually impossible tho
