Confused and need a new car. Shall I buy a Citroen 3?

[Blu]

I have only ever bought one car in my life - my current clapped out Fiat Punto. It is ideal in terms of size and economy for our one-child family. I need something nippy and small, but spacious enough for the occasional camping-trip with all the gear, so somethiung really tiny like a corsa or micra won't do. Also do occasional long drives.
I am not at all bothered about image or status, and do not want to pay for anything more flash than I need functionally.
I don't want a complete banger.
Good second hand cars with guarantees and warranties seem to be about £4-5k.
Citreon have an offer, £6,690 for a new C3. 3 year warranty, 12 year corrosion warranty. Should i find the money and buy one, if not, what shall I get and how should i look for it?
I would never be able to tell if i was being ripped off by a dealer.

eeek!

I have never before considered buying a new car because of the depreciation factor - but only this time because of the 'cheap deal'...

eek...

I have recently got a Suzuki Wagon R (R reg for £1000).

We wanted a Perodua Kenari (a joint venture between Toyota and Daihatsu), but were looking around £4000 for 2nd hand which we couldn't afford.

Basically the same car - different brand

Very small engine size (under 1000cc). Reliable reputation.

Big bonus is however that they are a decent size inside. Look funny (bit like a mini people carrier), but I really like them.

I think they are perfect small family car. Decent size boot space (hatchback), good room inside and very economical to run.
