I haven't but when did that stop anyone on the internet from commenting? It looks like a decent spec for the money to me. It won't stand up to extreme conditions but that shouldn't put you off. Depending on how many of you there are you may well want to add to porch to it.
This is a 20' long 7' high tunnel tent, it weighs 26kg this is a monster tent, you could probably park your car inside it.
You will need a massive pitch and if it's erected sideways on to high winds the poles will take damage.
Do you really need such a big tent?
Myself, partner, 3 year old and two teens are camping for the week. We’ve booked a medium pitch at sandford Dorset. Maybe I should look at down sizing then if it’s that big!
If you're going to Mendip Basecamp. Mendip Activity Centre, Lyncombe Drive, Sandford, Somerset you'll probably be ok as it's open field camping but you'll have to arrive early to get a big pitch.
Many more organised campsites have marked pitches and you'll have trouble getting your tent let along your car on the pitch. you could of course over hang into the next pitch and park your car in front of their pitch. As a new camper you may wonder why the people in the next pitch always seem to be so grumpy, after all they are on holiday.
If its the Park Dean site I wouldn't worry too much about tent sizes.
I camped at Nodes Point on the Isle of Wight and some of the tents there where huge, bordering on circus tents. No one seemed bothered about pitch boundaries and that was during the COVID silly season.
