Vauxhall Vectra 2.8 T V6 VXR 5dr 2006 (56 reg), Hatchback
FULL BLACK RECARO LEATHER

Vauxhall Signum 3.2 V6 Elite 5dr Auto hopefully about 2007?
-----------------------------------------------------------------------
3.2 V6 Signum (or Vectra C) is not available in facelift - 54ish plate onwards, they dropped it in favour of the 2.8 V6 Turbo.
Ive owned a 3.2 V6 and currently own a 2.8 V6 Signums of the 2 the 2.8 is better of the two, the thing to look for is that engine has a small issue with chain stretch, Vectra & Insignia VXRs have had most of the issues, some have high millage, some low, some tuned some not, some 255 some 280's have gone, there is no pattern to it, BUT I've not heard any issues with the 230bhp version yet, even though its effectively the same engine.
Listen for a rattle on start up and during tick over.
Chains and tensioners are not a service item, apparently never need changing
Coil packs can go, there are 6 individual packs, about £80-100 each in the UK or £190ish for all 6 from the USA delivered including import tax!
Purge valves 'fail', basically the car will run and start fine, but when you fill up with petrol its turns over for about 6-7sconds before firing up, it ONLY happens when you fill up and you won't know its a problem on the test drive unless you want to put some petrol in it - new valve is less then £30 and takes 20 mins to fit
Apart form that its just the standard wear problems. The base engine is used alot in America and Australia and used in the SAAB 9-3/ 9-5
The bonus is no matter what version you go for - 230, 255 or 280bhp, a simple remap will give close to 290bhp and 400lb-ft on all of them :-)
Remember any of them registered after 23rd March 2006 is in the £490 tax band, but mine is an 06 registered on 21st March 2006 so comes in at £280/ year :-)
Another point, save money, don't buy the VXR it'll be around £5k and up, elite spec cars with same engine and more toys will be around half the price! VXR's are not all as well spec'e as you might hope
Before I got the Signum I was looking at the 3ltr ST220 and X type, couldn't really find anything 'major' wrong just they were considerably more expensive than the Signum/ Vectra of same age and same miles
