Well you could buy a Corolla from Ireland , though LH drive
Whats wrong with the UK Auris partic the nicer looking 2015 on model, virtually a Corolla or even the newer larger Yaris ?
Sat in a showroom Prius the other month, feels very big and plush, its the long term price of the battery that would concern me ?
Are you looking at new, nearly new or a few years old ? - your old car should be worth something trade in, just do not accept their first offer and keep mentioning online prices to let them know you could go down that route; never a good deal for you till you see the salesman crying
Been meaning to try out the latest Astra, the reviews say its even beats the Golf in many areas, partic ride comfort which I need with these old bones
