I'd get something smaller, and invest your money in good beds/SIMs/sleeping bags because that actually makes a lot more difference to your camping experience. Something like a 4 or 5 berth tunnel Outwell or Vango. Still tall enough to stand up in and with some nice windows. If you do (like we did) upgrade to Behemoth-of-a-tent then you'll have something for weekend trips. If you don't like camping much, you still have a tent for using occasionally.
We have an Outwell Wolf Lake 5 (old style) and it's been brilliant in all weathers including scorching France, hurricanes and midgy Scotland, but then we are diehard campers and that's our main 2 week holiday every year. We also have a smaller,easier tent for weekends/festivals.
You need to think what you can fit in your car as well!
