doors -how to keep open when getting out?

[magpies]

I have an S1 which does not have anything to keep the door open when entering / exiting the car and this can be a pain - hilarious to onlookers too. This also re-inforces the TVR is a kit-car miss-fact.

Do modern TVRs have this problem or do they have a device - if they do a photo would be good.
