can you get isofix retro-fitted to an older car?

[thisisyesterday]

just wondering, and if so how much does it cost? does it make it worthwhile buying an older car and then getting it fitted, or is it easier to just buy a newer model that already has it?

no you can't as it has to be built into the car seat itself.

ahh s'ok i just found out that you can! lol
searched and came up with a volvo forum which, coincidentally is what we're buying and you def can on some models, will have to double check you can on the one we want.
only £78 too! so bargain
