Agreed the shell is very similar to previous 110's but I'd argue that there were some cost cutting done on the PUMA, for example my TD5 has large amounts of seam sealer applied to the seams throughout the body, including the seat box. This sealer is under the paint so was done as part of the manufacture process.
The PUMA has none at all. And daylight visible in places through the seams.
The TD5 has black underseal applied underneath the body, PUMA has none.
Congratulations on the leak free Defender - just goes to show there is hope!
