my better half had one of these(vectra b) tbh thought it was agood car for the money when we got it, had full leather as well, had 92k on when we got it then it started falling apart
done 10k in it and had the following parts
outside temp sensor,oil cooler,battery,glow plugs,steering rack,track rod ends,ball joints, arb links, cv boot, arb bushes
abs pump was knackered when we sold it
this was when i worked at vauxhall and the lads did warn me about them but was all we could afford at the time
in my opinion not worth bothering with, couldnt get comfortable in it either
engine noise got on my nerves and in the end couldnt live with it any longer and got her a mondeo sttdci, in a different league to the vauxhall
if the diesel pump goes that not cheap either
thats my 2p worth
