Hi Kelly, 

It depends which Tiguan you mean and, more importantly, how big the child seats are. If you mean three ISOFIX seats then the answer is an easy no, as only two ISOFIX mounting locations are available. However, if you're not talking about ISOFIX seats then you may be in luck. The current generation Tiguan has an especially wide rear seat with a particularly wide and flat centre section, making it better than most SUVs of its size at fitting in seats. Obviously, the size of child seats varies considerably, so the best advice we can give you is to bring the seats with you when you go to check out a car and see how easy they are to fit in.

Incidentally, there is a longer version of the Tiguan, called the Allspace, that has a third row of seats, which would certainly make your life easier if your budget stretched that far.
