Similarity or differences in Current Defender models

I'm looking to buy a Defender Crew Cab 130 but here in Germany, since the end of last year, new ones aren't available and there seem to be not many used ones for sale.
I was hoping to check out a Crew Cab at a dealer but for the above reason, can't. Here's my question, which I hope isn't a silly one or one to which the answer should be obvious.
Is the driver/passenger area in all current (newly manufactured) models identical or are there differences between, say, the driver/passenger area in a 90, a 110 CSW and a 130. I'm thinking of things such as leg room and so on. If I sit in and drive, for example, a 110, can I assume that a 130 would feel (and be) the same, or is that a risky assumption?

From the interior bulkhead behind the drivers seat and forwards is exactly the same on all vehicles regardless of whether its a 90, 110 or 130. CSW's won't have an interior bulkhead and will allow you to move the front seats back and recline them a little more but apart from that they're identical
