Thanks for all the suggestions, ladies. I'm almost 6' in height, up to 6'5 in heels (although I usually keep a pair of driving shoes in the car and switch, but I get in and out the car in heels).

We do have a wide range of cars over here - some of the names are a bit different (eg your Tiida is my Pixo, I think) but we do get most of the main brands. I'm not too worried about squeezing into the car, just that I can sit like I do in a proper seat - or as if driving a 4x4 - as I find those cars easier to drive and my driving improves in those as my arms reach the wheel comfortably/the wheel isn't on top of my legs. (DH doesn't have this problem and prefers to sit with his legs in front of him, which means he is NEVER allowed to pick a car for me again, the last one he picked was uncomfortable to drive and had other issues. Not least that it's written off now.)

eta - I'm on a limited budget, so would prefer less expensive cars. It's just for getting me to work and back so doesn't need to be large or fast, for long trips/holidays we will use DH's car. Plus parking space is limited at the front of the house, so we need something small. A really small one may fit in the garage with DH's old mini, which would be a bonus!

Any more suggestions?
