ok thats the first thing ill ask is if they know the milage when it was done. anything else i need to know?
On paper sounds ok, if cambelt been done in 07 as they say.
Bear in mind Omegas are cheap anyway and there are loads about, so no need to rush in if not 100% happy.
Choice is down to what you personally want, some want cheaper costs, some want power and spec.
I have a facelift 2.2 auto and have done a lot of work on it, which with most other cars would have not been worth it.
But with OOF and helpful members, I have turned around a tired 100k car into a very good one, fairly cheaply.
FYI the consensus seems to be that the best balance of performance and economy is a 2.5 V6 manual. The 2.0 is a bit underpowered (and many say the 2.2 is too).
Check specs before buying-the GLS is the basic car and you will find a nice CDX for not much more.
Are you familiar with the obvious things to look at on any car, like oil/water etc?
