I own a Hyundia Lantra, if I do get there on tuesday before you leave I will show you what my probelm is. But basically there is not enough room. When I first put it into my car with the base I thought beauty! it will fit & once I got home & fitted it properly, it was a very tight squeeze & the other 2 seats (1 is a normal reversable baby seat, the other a Hi-Pod Booster seat) where not dead centre with the ancher point but I still thought it doable. Then I tried it with out the base & it made the primo to low so its sides were clashing with the side wings on the other 2 seats. So I put the base back in & tried it all again but I just couldn't get it all to sit right. I got it all in just as well as I did the first time but my biggest problem was that Evans Hi-pod seat uses the seat belt to hold Evan in, it doesn't have its own harness set up like the baby seats. So I needed acsess to the seat belt clip & it was near impossible to get to it easily. It was very awkward & I could see that over time we would get lazy with being "ontop" of making sure it was all secure each & every time we got in the car. I mean don't get me wrong, we would still have strapped Evan in etc but I could see it becoming a pain in the butt & short cuts being made. So I decided it was too much hassel & probably too much pressure on safety.

I have since had the idea though of Down grading Evan from the Hi-pod he has (with arm rests & cup holders etc) to the basic design. it may be a bit smaller & it may work. I will need to suss it out. I would be much happier to spend yet even more money on car seats & have every one as safe as possible then to have Evan on a under the bum booster. They just don't sit well with me...
