If you search on Carzone.ie for cars between 1000 euro and 2,999 euro you'll find a lot of choice. I wouldn't buy the Rover because it wasn't considered to be a particularly good or reliable car in its day and as another poster has said, parts availablilty may be a problem. You may also have difficulty selling it on in a few years.
If you're buying from a dealer, try and buy from one that has a decent trading history and is an SIMI member. SIMI membership, while not perfect, will give you another option if there is a problem with the car that the dealer is unwilling to help with.
If you google the dealer name in question along with the word 'problems' you might come across more info on them.
