Best out of these

Probably the Skoda. The only reason I didn't get one myself is because they didn't offer a car in between the Fabia (too small) and Octavia (too expensive to insure) within my budget so I ended up with a Golf estate.

That model Fabia have a habit of burning through quite a bit of oil.
That model polo tend to eat injectors which ain't cheap.

The silver fiesta looks the cleaner of the two, but it's obviously had some sort of bump on the front o/s corner. Bumper is misaligned to the wing and you can see where the skin has hit the armature around the tow hitch cover.
The blue / black fiesta looks like it's got a really dirty interior.

I wouldn't bother with any of them.

Dirty interior would be the least of my concerns, are you saying I shouldn't pursue the 03/04 polos?
What do you recommend I get for a 1.2 thats £2000 or under

Even better....

What about these two?

That's just 10 minutes looking of autotrader. You'll easily find something with silly low miles in budget and in nice nick.

When do you recommend I should take the car to a garage to get the water pump+cambelt replaced? its done 76kmiles and its 04reg

Now.

Interval on cambelt / waterpump is 10 years or 100k on a fiesta.

Good luck with it...

My cheapest quote I got to change the cambelt+waterpump+auxiliary belt was £350, is that worth it?
