Have been driving a smallish peugeot 307 which finally went bust 
In the early stages of my driving after passing my test early 2012 I managed to scratch and scrape the car a bit
(mainly parking and bumping into walls and gates). I still dislike parking and driving in tight spaces.
DH and I share a car. He wants us to buy a vauxhall Astra as he has driven them for years and says they've never let him down, and we're very limited with choice because I can only drive an automatic and we have a very narrow budget, so there are quite a few Astras available that fit our criteria, except I am really wary of driving a car much bigger than I am used to given that i'm not the best driver , I'm also quite tiny ( I do have to prop myself up with cushions in the driver's seat so I can have a decent view, FWIW am barely 5 feet tall and wear age 11-12 clothing). I would LOVE a little micra but DH's work requirements means he travels all over the country and does ALOT of mileage and needs a bigger car.
SO AIBU to be really wary of driving a bigger car or is it fairly easy to get used to?
